Major League of legend bug???

Story:So today, I got on and decided to play some league of legends. I played a few games and stuff, but then out of no where, LOLclient.exe has stopped working. I thought to myself, "Oh well, it just crashed", and just got back on and decided to play a One for all game. I got into champion select and when the champion selection screen was finished, my game just got a bugsplat, and I was like "What the fuck?". I decided to restart league and repair my files. All of a sudden, a screen popped up saying that "update failed, Unspecified error occurred. Please check the logs for more information". I noticed on my tool bar that there was a pop-up saying that a certain folder which is the DrMundo/Skin/Base was corrupted and unreadable. I don't know how to fix this problem, so I decided to delete the DrMundo folder. When I tried doing that, it said something was corrupted so the folder can't be deleted.

I have no idea what to do. I can't get rid of the error, I tried everything that everyone told me but nothing works. I really need some help. http://imgur.com/a/QZs7x http://imgur.com/az5i15y
