Hi,
I'm trying to start a weekend setup in AC using CM (FH19 at Donnington if you want to know), but the damned thing will not load. It gives me this tiny window that's usually the game window and keeps 'waiting for the end of the race' until it finally cancels the session. I've verified the integrity of my files. What's going on?
