Possible Fix for "Calculating Diffrences"

I placed this in a thread that people were complaining about this in but it was ignored so I will post it here for every one to see. The steps I took were as such.... 1- Attempted to repair league of legends which did not work it simply went back to calculating. 2- Attempted to uninstall league of legends from my computer, which did not work (the uninstall wizard never showed up and it was removed from the list of programs). 3- Deleted the league of legends folder and everything in it. 4- Re-installed league of legends. 5 - Played a game and tried to break it again by alt + tab, which did not break the game and did not kick me from the game. Everything seems to be working for me now maybe someone else can try and leave a comment on whether or not it works for everyone.
