Scanning/Repairing/Updating Bug HELP!

Okay, I got home from school this afternoon, and my friend was very excited to inform me about Urf coming out really early. Naturally, I was excited as well. So I booted up League of Legends, but was gifted with the opportunity to experience quite a bit of pain. I logged in, noticed that League of Legends was updating. How nice, I suppose I'll wait. Zero percent. Couple minutes pass, three percent. This'll take a while, so I hover over it, and it stagnated from 459.9 mb and 250kb/s, both not moving. I figured it was a visual bug, as the % was still rising. So, I wait, and wait. Then, randomly, it went back to zero, and when I hovered over it, it was scanning files. Me being confused, unable to comprehend why, I waited. 3k files scanned. 0%. I closed League and relaunched. Then it was scanning from a countdown instead of a countup, from 3k or so, until it hit zero, in which i was finally allowed to log in, and I don't know why it restricted me otherwise, but http://prntscr.com/g6zbnv . Yes, my internet is just fine. Logging in, it wouldn't allow me to press "play" as it was greyed out, and requested that I relaunch the launcher. So I did, but it was once more from a countdown without the option to log in once more. Thus, I did a "full repair" thing. Which, after a long while in the 2nd phase of it, was prompted with this, http://prntscr.com/g6zplb . So I closed it, relaunched leage, and here we are, currently right back in beginning of the loop of http://prntscr.com/g707aj . Please, I really want to experience Urf, and it'd be much appreciated if any were to help. Cheers.
