Thx for your help @Tumbler31 & @airtex2019 : now the U2 runs fine w/o CTD. I now have to test in flight but at least BMS doesn’t crash anymore when launching.
I never suspected “C:\Program Files (x86)” install to be a problem as 1. I have no specific knowledge in IT 🙂 & 2. all over games (including BMS since I began with 4.34) run perfectly in this repertory.
Thank U one more time for your time & your kind answers.
Cheers,
Hawk
