Can't Play LOL :(
My brother and I have been playing League on a new desktop since January. It has worked flawlessly until Wednesday May 18,2016. We are able to log-in and queue up into games, but when the game starts it brings us to "The game has crashed" screen. It also pulls up a tab saying: "The instruction at 0x77860fb2 referenced memory at 0x025d2afc, The mamory could not be written.
Click on OK to terminate the program."
How do I fix this?
