I've already posted that I'm having the same issue. Got stuck in a Tele-Yhoat and can't get out. Nothing was changed on my PC, and when I log my 2nd account in on my PC, I can log in and Tele-Yhoat without any issue. I can log in 18 other characters just fine, just can't get my main in. Yeah, it's an ISP issue. /sarcasm

So now I just have to wait until noon to contact Customer Support per a GM call I made. Fully prepared to get jerked around some more.
