I only got the game a few days ago, but it's just happened yesterday.
Only things I've downloaded are kits and logos but been using them since I started playing.
Wanna start a new game but don't dare cause I'll click transfer history and it'll break. I know it's not a massive error just annoying cause I like looking at what transfer teams have made
To take a screenshot just press 'f12'. Might help, I'll try figure out what else it could be.
Try starting a game without any of the kits/logos in case it is something wrong with them. Where did you get them from?
EDIT: Also, have you tried starting a new save and it still does it, or have you only done one save?
Try deleting the crash dumps folder (Sports Interactive>Football Manager 13>Settings>Crash Dumps)
Yeah real game, only brought it other day, was bargain at £20 from game, well when it's working okay it is hahaYeah started a new games and still the same, just deleted all my football manager folders, dunno if I should of lol
