@RXP Problem solved also for me. Thank you very much!
Can you please confirm the following facts for my understanding:
1. The root cause for the blackout screen in X-Plane has been the false positive warning and could been addressed by asking Windows Defender to skip the Folder "c:\Program Files(x86)\Reality XP\" - Correct?
2. A re-installation would not have been necessary! - Correct?
3. The re-installation problem was fixed by the new download links you put into the installer "rxpGTN-750-XPL.exe" which you updated on the Reality XP Website last night (for me). Therefore my installation was now successfully.
4. I did understood now, that the Garmin trainer application has not to run in parallel, as it is just used to provide the databases for the x-plane integration. Correct?
Thanks for letting me know and ramp up my understanding of Reality XP Plugin.
Best Regards, Markus.
