patcher..

i click the cf icon and the thing comes up were i hit play now... i hit play now and nothing pops up at all i go to do it again and it says patcher is already running..i have to go to task manager to end the patcher but it still wont load after i end it.. ive never had this problem in like 3 years of having cf downloaded i dont understand how i was just playing like 7 hours ago and i log off and this happens ive restarted my computer 3 times and that has not helped
