Crash when I do anything.

Crash when I log in. Crash when I change masteries/runes. Crash when I talk in championselect lobby. Crash right before pvp.net client starts game so I have to relog in after the game ends. Cant report or do anything .

Consistent connecting to PVP.net dialouge 4/5 times before It crashes. Bugging everytime I accept Q. Sometimes doesnt show up at all. Crashing in ranked promos. Happening to multiple accounts. Did everything in the bugs report menu. Reinstalled Please Help, constant problems since SEASON 2.
