ARMA2 OA HAS STOPPED WORKING

[SlutMonkey 1]

I stopped playing a couple of night ago and DC out of the game, and I have not bee able to play since. I get in a lobby. I click OK to enter the game. It gets to the loading screen with the loading bar below the tank, and then the game crashes, "ARMA2 OA HAS STOPPED WORKING". I have been trying different techniques for 2 days with no luck. Any help would be most appreciated.

Thank you

This is fixed by running arma 2 and arrowhead once in single player. no more bad serial number, now i just just crash after loading into the server yaaaay!
