Hey there!
So, it seems like I am unlucky one. I was trying some addons for my guild and one of them did something with controls, turning ESC button into UI remover! I press ESC, all UI hides but chat, pressing it again doesn't do anything, I can't reach my control options to rewrite them manually.
What did I try:
DELETING every addon I installed that day.
REMOVING all the addons, Addon settings and User settings.
UPD: tried to remove the whole "live" folder - nope, I can't even skip videos before login screen, ESC button doesn't work.
Didn't help. Nothing does.
Then I tried Repair. It went through once and then started doing it the second time and got stuck at this

Aight, I tried running with Administrator rights, didn't help, stuck at the same place.
I tried uninstalling Adobe Flas Player and redownloading it from the official website. It didn't work either.
I tried to send a ticket, and guess what? This is how my "open a ticket" page looks like:

So, what could be done to restore my controls again?
Also, don't be me, DO YOU BACKUPS!
