Just downloaded and installed the latest patch. Going online appears to work (although I haven't actually flown yet). However, if I try to go to offline practice, it preloads all of the textures and right as it should be entering the arena, it crashes to a white screen.
I ran a scandisk, moved the sounds folder out of the Aces High 2 directory and deleted the cache. It still crashes when going into offline practice.
Before the patch there was no behavior like this and no other change to my system other than installing this patch. Again, the crash only appears to happen when trying to go into offline practice.
