no reason, just disc. tried it on one different pc, same error. (disconected from server, no other error). talking now with a gm . I asked him to teleport my toon somewhere else, and it worked (now I can log in). he also said that clearing the outdated cache could fix it. (repairing wow using repair.exe ) e1. worked for like 30 seconds , got disconected... will try repairing. I teleported him in valiance keep and it got disc again... and now I can't log on him again
