If you're using game capture and you get this, this means that there's undoubtedly a conflicting hook program active. Another capture program, such as fraps/etc, or an overlay program such as teamspeak overlay and such, or graphical modification programs such as sweetfx. Sometimes vendor programs such as MSI afterburner can cause this to happen as well. All these things can interfere with game capture and cause a crash in the game itself when game capture tries to activate. See if you have any of those programs running, and if so, turn them off.
