Kicked In the middle of a Que

I keep getting kicked from the client cause it "Needs to restart". Then I got brought back to an older version (maybe an update that overpowers Windows 8.1?), then it says I can't download it cause I need 8 GB space on my laptop, which I have 689 GB space free! I need help!

Now I'm about to get penalized cause it's gonna say that I left during the champion selection! :(
