Last patch before they changed the Jax and Corki splash yesterday, I could play the game completely fine, no hassles. Right after they added this patch I could get into the client, go to the store, get in a queue, select a champion, be fine. But the game won't start. It doesn't open up the little pop-up. A couple of times it had a bug-splat error, a couple other times it said I can't run the shaders.. O.o How can one patch cause my client this much error. After restarting my computer twice I was finally able to rejoin the game to a DEFEAT screen. I have been reported for leaving multiple games when I can't help it. At first I thought it was a one-time error so I joined a new queue and caused another defeat -.- HELP!!!

It's happening to me as well... please fix this

I also should note I am using Bootcamp through a Mac to run the game

I'm using windows vista
