Hi Dirk,
thanks for this report and the details.
First, no its not possible to revert back to an older cycle/revision. I have compare the files in this area betweenl AIRAC 2014 with 2101 and they are identical. So it also wouldn’t be make sense - or do you mean a special cycle?
Second, I haven’t tested it at the moment but as I have understand you, that the same flightplan which you are created in SimBrief is working (no CTD) with the stock data and the CJ4 mod?
A few things:
Have you flown this with a default aircraft also?
Please contirm, you are using the latest Navigraph Installer beta 23?
Please confirm, you are the latest Cycle 2101 rev 3?
I read you move the navdata folder … you shouldn’t do that because we disable the stock data in the client and when you move the files manually, it can result in an unknown state. So please use EVERYTIME installer (remove and install the dataset).
Last, due the not clear system situation, I woukd recommand these steps here.
Cheers
Richard
