if u get this error, instead of restarting comp or repatching simply go to ur task manager, go to processes and look for gameguard.des should still be running even though your game is closed, just right click on it and click end process, it will close, close task manager, look at ur quick bar in the lower right and make sure its not there, somtimes the icon hangs, and re launch game, and bam instant fix.

plus please check my other thread as my game keeps crashing ta
