Please Z8, I'm Fed Up

Even after this new patch, whenever I log in I get a message saying "Server is full" then I click okay, then it says "Disconnected from server." I had a problem before this were it would say "Hack tool detected." I am just so angry and I really want to play, im taking a break from COD and want some more Crossfire!

NOTE: I've tried everything to counter the problem, disabled anti-virus, re-installing, and constantly dying of insanity.
