Dude it's like 5 bucks on ebay. I rather pay the 5 bucks then download 4 gigs. So I did. It cost me 9 bucks including shipping. Free map too. I don't belive you don't have 9 bucks. Do the Same! (Probably doesn't matter now as your getting banned
)

But speaking of the problem, this is exactly the same problem I have. its a game crash. It looks like an incompatibility with some systems or a windows bug. I'm waiting for a patch.
