WTH , So two locale file problems so far and then LOLclient.swf file problem..... And I imagine I'm going to have treplace all these files on both PC's

Was there some kind of major corruption while I was away from the game ?

I recently got a new sick pc, but after downloading LoL I get this message error. And the answers are just all over the freaking place, and (embarrassingly enough) I'm not savvy with tech. I could really use help, I've reinstalled more than once already. Have never changed and files, be it for mod or anything otherwise. I know you gotta be tired of answering these stupid question, but I haven't gotten to play in months now. Don't wanna lose out on a great game cause of my "user error." Thanks!
