I'm writing this for my brother right now who have some connectivity issues. Yesterday, he tried to log on with his character to join me and my guildies for a few runs, but the loading screen between 2 instances was taking too long (around 5 to 7 minutes without any progress in the loading bar) and he close the client with the task manager. He logged back on, but they didn't let him in, as the game said the character was already logged in this world. (I checked through friend's list and he is marked as offline)
He logged in with another character without any problems, so he logged out and tried to come with his main, but he got the same message. He exited the client, close everything. He even rebooted his PC, but to no avail.
Now, more than 12 hours after, he still can't log in. Still says that the character is already log in. What are his options right now?
