Crossfire giving me weird error after starting up.

After it loads up and before it goes ingame Xfire gives me a weird error saying that a external program is causing incompatibility and needs to be closed.
It has NEVER done this before, what should I do?

Stop using xFire because it sucks.

Well nvm now its working, was trying to run it with GB3 but its not compatable with it.
Also yeah I know but it requires it :S
