I also have the failed to join but i think i got my IP banned because first off all of my accounts and all characters get Failed To Join Error. I try reinstallin the game with Different Cd Key for LOD and Classic. Doesn't work but my friend goes on my account and he can join games ppl say that it might be of a trojan or is that tru i don't no? or did i just banned for like 1 month or what?
