Cant play Wave Mode

So I just got my internet back after moving and I had to update CF when I first get on.

When I load into a Wave Mode game (loading screen) the Screen goes black with the music playing in the background. Sometimes I can get pass the loading screen but within 5 seconds in the game itself the game crashes. I have to ctrl+Alt+Delete to exit the black screen and the game crashes. There is a "Send error report" when I come back to my desktop.

I have re-installed CF but the issue still occurs.
