I had frequently CTD’s too. I could find the cause for my CTD’s by extending testing and found the use of framegen was the cause. Some one adviced me to do a windows repair and that solved it for me.
First step; check if you get CTD’s without framegen on. If so do a windows repair. Note that some programs need to be re-installed afterwards.
Allthough so far I could just 5 test flights and it i’s a bit soon for a definite conclusion I am feeling much more confident it is solved.
