Game crash after champ select

Hi, im encountering a probleme since last patch, not sure if its du to the league patch or me updating my graphics driver but after champ select when the game tries to launch it instantly goes back to client with the "reconnect" button and wont relaunch no matter what I do. I tried the obvious: reinstalling, reparing, hextech thingy, reading past posts that are similar to mine but not exactly etc etc. And now I rly dont know where to turn to... Iv NEVER had any problemes with league before and have been playing since S2. Any official help, or otherwise, would be GREATLY appreciated.

Thank you fellow summoners!
