A critical error has occured and the process must be terminated

Yup, as the title says. Right now while I am typing this ticket I cant play LoL and everytime I reconnect to the game I can wlak for like 5 seconds and get kicked out again. I tried a few things already, 1: Updating Gefore Experience 2: Restarting my PC 3: Restarting LoL client I hope I dont get a *** leaverbuster for this, and is there a fix out here?
