Just played it about a week, smooth, no problem. And now, after i login>select char it just close and theres this dialog box saying "you have been disconnected from the login server. Please try again." What could be the problem?
When others have your issue I see the following being suggested. If that doesn't help, create a thread in character issues for a GM to look into it further.
Then you need to create your own thread in the 'Character Issues' section. A GM will be able to see what the issue is for you.
