Calculating differences 11000 files scanned 33%

If any1 else has been having this same problem with the latest patcher and fixed it,, please give advice. When I turn on my patcher, it starts calculating differences and scanning files: no surprise there. But then it just keeps on scanning files from there. Mine went up to 11592 (after an hour), and shut down. From there I uninstalled and reinstalled LoL, and it worked--partially. The patcher got to 99%, and stopped. After waiting an hour, I looked at it again, and it was still stuck. I closed and re opened it, and it start endlessly scanning files. Riot, or someone who had this problem, please help me out!
