0% 10k files scanned (patch 6.8)

Have you tried exiting the client and running it back again?

you have a really slow computer, though for me its kind of normal for it to scan at 0% go through about 10k+ files then jump up to 33% and so forth. it should take about 10 minutes... dont know why yours is taking 2 hours

This is what i tell my parents 99% of the time they have a problem with technological things, I say turn it off, then turn it back on. Most of the time it works. So just do a restart (:

same happened to me since i tried installing LoL on my laptop today.. I did try to reset it but nothing. I was playing on my computer just a moment ago and it seems like the game has been hacked or something happened since there's almost 14k people logging in at the same time so i had to wait 5 minutes just to log in, and there was a huge delay in champion select, i had to wait maybe 15 minutews for the game to start and then a lot of people are afk in games..
