Basically, I was in-game editing settings, Whenever i click "Apply" i get that stupid "Kicked for broken .PK3 files", This only started happening after i added the new custom Defrag maps to my Maps folder.. And i would also get a Black & White striped boxes everywhere and it's horrible to see..

Anyway, I clicked "Apply" and when re-loading the client it said this (With a grey screen):
** GLW_CreateWindow: could not register window class
Please report the the problem you encountered on the Quake Live forums.
You must reload the web page to make this display go away.

That is an Exact copy of what it said (Even with the fail Grammar typo "The the")

How do i fix this? And how do i also Fix the stupid Glitch with vid_restart?
