I spoke to you last night about this for you from my shop alt, actually.
Now that I've gotten some sleep and woken back up, I remember a fix to this that used to work several times when it happened to me.
Open your patcher and click on "Graphics". Make sure to turn everything down, entirely, and start the client up. See if that'll help. If not, then I really do not know how to get it to work.
Good luck!
