Hi i have a bug when every time i try to log in it crashes with the above statement anyone got a fix? And im not downloading LoL again unless i really have too already had to do it twice already with previous bugs -.-

Not sure, do you have to wait a long time until the error message comes up or is it instantanious? If you're running vista/7, have you tried running it as administrator mode? Have you made any hardware or software upgrades? Are your drivers up to date?

even after the wait it crashes just says close program.

i reinstalled both LoL and adobe air now. Still crashes
no upgrades.
drivers updated

I suffer from the exact same problem, hasn't happened in a week or two so I'm just waiting till I'm next in game for it to die T_T So far I haven't been able to solve the issue PC side so I guess it's just another problem Riot have to sort it out.
