I have just downloaded the TERA game, I am so excited to play this, but I am am not satisfied, because after installation I put my email and password, it is showing me "User Authentication Failed" what does that means, if your company really wants to gets the interest of the peaple at large so you should solve th problems and not to make any condition like your region are allowed yours not this is sucks. I never expected this from your company and so if you really cares yours customer or player or members so please I request you to solve this problem!
