Has anyone come across memory problems with this game? Ive had it for ages and not had any issues with it but at the moment when i try and play it after say 10 mins of gameplay it crashes out saying the game is low on memory and will now quit. Ive run it for ages on just 1gb of ram so i thought maybe my c drive was getting a little low on space wich it was on 4gb left, ive sorted that out so theres now over 10gb left but its still happening any ideas?
