Still gettin D/C'd every time I log in game

M'kay, this has been happening for a while now, for pretty much 2-3 months. Everytime I log in game, I get one of three errors, either: usually 'disconnected from server', rarely 'hack tool detected', and even rarer 'unknown error'.

This is becoming a bit of a bish for me, but since I don't play CrossFire too avidly, I haven't really moaned about it here.

I don't get this problem in any other online FPS games I play, so I'm guessing it's something to do with CrossFire, but my internet connection can be dodgy at times, so I won't rule that out.

Anyone got any solutions to this?

(I'm running GameBooster in the background, but it makes no difference it I use that or not, I still get D/C'd)

P.S. Don't say uninstall/re-install, I've done this numerous times, with different downloads each time.
