Crash in UT mid game after 5-20 minutes..

EA, when are you fixing the AntiCheat? The game works fine in Kick-Off, Career, even Rush or Squad Battles, but in Rivals it crashes and in the Event Viewer shows an error like "ea.anticheat.service.exe", what are you doing? There are hundres, even thousands of players with better PCs than mine and we can't play the game because of crash ... do something as soon as possible.. didn't spend money just for not playing....
