Hi sphinx1912,

you may have a look in your cache folder of your UP3 and delete the files there?
It might be just a hick-up... hopefully.

Jambo :wink:

Thank you for your help. Where is the cache folder located within UP3? This is getting really weird because everything was fine for the longest time and then it just started doing it despite my not having made any changes. I have since deleted everything and done two complete reinstalls and several copy and pastes of my IL2 file. Now, everything is fine during my first outing, but during the second or third, it craps out. Whatever the problem is, it seems to be taking place around the 70% loading mark because I get the swirly Windows 7 icon popping up on the screen and that's when QMB will fail to load.
