Thanks for the reply Jim. I've backed up the .cfg file and allowed it to rebuild. Maybe there is a better way than that. But I just renamed it and moved it to my desktop. Also, I've made sure all my admin rights are set, but it's possible that I've missed one. I verified that fsx.exe opens as admin, this is something I fought with back in windows 7, but resolved. This was the first thing I did upon starting it in win 10
EDIT: I'd like to add that my CERA UH-60 is working properly, but the base and other addon aircraft are the issue ones.
