CLIENT--Game won't load

Downloaded the 6.5 patch update and played the game fine on Wednesday.. Now I'm trying to login but it is "calculating differences". I've been sitting here for 2 hours and it has 10000 files scanned and it still won't let me login to play!.. Yes I have tried clicking out of it and it started over.. big fu***** mistake... RIOT --- if you truly feel bad please fix this problem OR gift me 'not so blitzcrank'.. I have all of his skins but this one, Thank you :)
