Techncial Difficulties
 

Hey guys.. I need help
I finished the level where you're supposed to order airstrikes on tanks and stuff to defend the Tiger Tank that you stole... Then I reached the Snowy Park stage... The game then started getting really slow for some reason... So I went out to the console area and discovered that in the multiplayer area I'm connected to some game (because it says disconnect from game at the bottom). So I disonnect and go back to the game and the same thing happens, and I find that I'm still connected to a game over the network. I thought maybe the problem could be with the saved game, so I went back to the defending the Tiger Tank level and won it again, and the same thing happened. So my questions are:
1) Any idea what's causing this?
2) I'm thinking of reinstalling the game, but would that mean that I would have to start all over from the bginning again?

Thanks for your help

lol, when it says disconnect on a single player mission....it means 'disconnect' from the single player mission
