Patcher & Update PROBLEM

I installed LoL 4 days ago, When I open it, it starts downloading around 1.2k mb of some update, then after scanning a few files, downloads 3,200 mb of some update, after reaching around 85% or above, it starts 'Applying Patches' in which it gets stuck every time and then after around 8 hours an error comes usually at 99%. I love LoL and I'm sick and tired of uninstalling and installing league EVERYDAY and trying to make it work and then after 10 + hours a error comes even though I just downloaded the file from the official site and didn't even touch any files?

CAN ANYONE PLEASE HELP ME? I'm also thinking about switching to DotA2 cause one of my friends suggested that it was a better game? What should I do?
