well i've had the game for a while and i've never had this issue. it's been updated to 1.4, and i don't have northern strike. and it only crashes when i try to join a server. i can log on to my account and pick my soldier, but i can't get on a server.
p.s.- updated punkbuster, but it didn't do anything to help. i also created another soldier, that didn't offer any solutions either.
