Okay, so i have had the problem all day, and i even uninstalled my LOL client several times. What ended up working for me was that on my last attempt to re-install the game and going through the patch update (when i would get stuck at the 33% on the VOBANK part) i clicked to shut off the peer to peer thing and then also clicked on Snugglie's temporary download and told it to repair the problems. (Which was the first option). It worked for me. Maybe try it. maybe without having to uninstall too. I haven't checked to see if it works in a game though. i hope it will.
