gamegaurd problem

I need the version for CF because I went to download the gamegaurd updates and my brother accidentaly discconected my wireless adapter. when i put it back in to download the updates again, the game came up and i typed in the username/pass and then it said "missing game file, cannot connect to server" or something like that.

I just downloaded and i am tired of warrock and i really want to play. plz help.
