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.
Which version of the ProSim 737 do you use? Please post a screenshot …
Cheers,
Richard
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
Richard, amazing thanks! I’m away right now but will post how I made out in a couple of hours with my Pro Sim and AS
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.

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:

Revision 3 is now online - please install the cycle again and let me know, if it is also working for you now. Thank you for your patience …
Cheers,
Richard
It works perfectly for me.
Many thanks for the help.
Marino
Looks good here now on 737 MAX.
