The update for ProSim 737 is not working. The ProSim database is not being updated. ---

Hi, Please can you give us more details … What do you mean by “not being updated”? You must run the database builder … Do you mean that the data are not available there? How do you update it? Via the manual installer or via the FMS Data Manager? Cheers Richard ---

Regarding the FMS Data Manager—I’ve been doing it the same way for years. ---

When starting ProSim, the data conversion process begins, but it aborts after about 3 seconds, and ProSim continues to display the old version. I have tried this on several different PCs. ---

Hello Richard, hope things are well! I’m having the same issue with Pro Sim A322, as well as my active sky P 3-D. Here’s what’s going on. **A322 version 1.75.1, failure at 2/8, and “NULL at ordinal 9” error. I have the log if you want me to attach that as well hopefully a little bit of help. As for my active sky, it just stays stuck on initializing.** Regards Shawn ---

Hi Shawn, Logs would be great - you can send them to me via PM if you like. Active Sky is a bit tricky because I can´t test it, but I’ll look into it as well. Thanks for your help Richard PS: I have the log here on my system - thanks Shawn 😉 ---

Hi Shawn, Thank you very much - I have still identified the issue but I must look how I can solve it 😉 Thanks Richard ---

Hi again, Fixed now … Revision 2 is still online. Please update it and try it again! Here from my B737: ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/7/d/7d32c9fce0cf3a056f12763a86b14fd4eaadece2.png) Thank you, Richard ---

No probs, Shawn - I have recognized another small issue in the database, but I´m unsure if this has any negative effect. I will fix this tomorrow and possibly release a 3rd revision 🙂 … even when it´s not necessary … Today, my day ends … have a nice night Richard ---

I have tested the new version with ProSim 3.37 and 3.38b 19, but unfortunately, it does not work. Thanks for the support. Marino ---

Just tried v2, unfortunately no joy for me as well. Shawn ---

It appears to be exactly the same error as before in V2. Error converting SQL Database: The data is NULL at ordinal 9. This method can’t be called on NULL values. Check using IsDBNull before calling, **the identical NULL-at-ordinal-9 error persists on A322 1.75.1**. ---

I followed some advice from the PROSIM forum that has seemed to work. ng\_jeppesen\_prosim.s3db.bak. I hope this helps you in the diagnosis. Thanks again. Shawn ---

I cannot install it to ProSIm as well. It loads default AIRAC. I am on B737 MAX. ---

Hi guys, Thanks, and sorry again. It seems I have uploaded the wrong file- it looks like it was too late for me yesterday. I am sorry. I have tested the fix again, and it works; there is no database error in the log any longer (as shown in my screenshot above - the database was created successfully). I will build a new package and upload it as revision 3 to make it clear that this is the correct one. Here my log from the latest test - no database error any longer: ```auto 10/30/2026 9:38:45 AM * Startup:Assembly=v3.37.0, OS=Windows 10.0.26300 Intel Core Ultra 9 285K, 1 CPU, 24 logical and 24 physical cores Process Environment Information: Runtime=.NET Framework 4.8 (4.8.10008.0), X64 RyuJIT GC=Concurrent Workstation 10/30/2026 9:38:45 AM * Startup:Application folder D:\Simulation\Tools\ProsimB737\ProSimB738 10/30/2026 9:38:45 AM * Startup:Starting ProSimB738 ProSimB738 3.37 build 3.37#1716+d2689e821b 10/30/2026 9:38:51 AM Running in mode Evaluation version with features ProSim737 Non-commercial 10/30/2026 9:38:51 AM * Features:Feature "Instructorstation 2.0" enabled 10/30/2026 9:38:51 AM * Features:Feature "Integrated Approach Navigation feature" enabled 10/30/2026 9:38:51 AM * Init:R&D [False] 10/30/2026 9:38:51 AM * Init:Args [] 10/30/2026 9:38:51 AM * Init:Initializing performance counters 10/30/2026 9:38:51 AM * Init:Initializing SimElements 10/30/2026 9:38:52 AM * Init:create splash 10/30/2026 9:38:52 AM * Init:set culture info 10/30/2026 9:38:52 AM * Init:show splash 10/30/2026 9:38:52 AM * Init:initialize components 10/30/2026 9:38:52 AM * Init:Booting system; Version 3.37, built 28 May 2026 10/30/2026 9:38:52 AM * Init:Loading configuration 10/30/2026 9:38:53 AM * Init:Initialize datalink 10/30/2026 9:38:53 AM * Init:Loading preset positions 10/30/2026 9:38:53 AM * Init:Loading global database 10/30/2026 9:38:53 AM * Init:Loading translations 10/30/2026 9:38:53 AM * Init:Loading navigation database 10/30/2026 9:38:53 AM * companyroutes.xml:File not found [.\companyroutes.xml], continuing without company routes from this location 10/30/2026 9:39:09 AM * Database:Loaded transition altitudes from navdata 10/30/2026 9:39:09 AM * Database:Loaded transition levels from navdata 10/30/2026 9:39:09 AM * Database:Loaded NavData database from D:\Simulation\Tools\ProsimB737\ProSimB738\DefaultData\NavData.dat 10/30/2026 9:39:09 AM * Init:Loading shared database 10/30/2026 9:39:09 AM * Init:Creating aircraft 10/30/2026 9:39:09 AM * Init:Creating aircraft Model [Ng] Variant [B738] 10/30/2026 9:39:09 AM Init: Loading Communication profiles from [C:\ProgramData\ProSim-AR\Database\Communications] 10/30/2026 9:39:09 AM Loading parameter set default 10/30/2026 9:39:09 AM * GPS:Loading GPS ephemeris data 10/30/2026 9:39:09 AM * GPS:Ephemeris data loaded 10/30/2026 9:39:10 AM Init: Loading EGPWS custom database from [C:\ProgramData\ProSim-AR\Database\egpws.xml] 10/30/2026 9:39:10 AM * Init:Loading datalink ``` Thanks for your patience.
