Changing time on PC

Well, Im not 100% sure where/when this happened in the client. I believe it was right about the champ select screen...

I dual boot my machine with Windows and Linux. After rebooting from Linux into Windows, my clock was off... a common issue... with an ez fix Im to lazy to do.

I ended up setting my clock back several hours to the right time and that killed the LoL client. It just stopped working during the champ select screen. Somehow, that functionality is tied to the PC clock.
