So here's the deal;
I CAN log into my actual wow account
I CAN'T enter the world of my main character, this is in realm thunderhorn, along with other characters I have which seem to log into the same realm fine. Once I click 'enter world' I appear in the world as normal, then less than less than a second later, it tells me I have disconnected from the server. I can't log into it and it is driving me insane. So, it's just this one character, and it will not let me log into it, Please help. Thanks in advance.

Ps. Do not tell me that my realm may be over populated, because I can sign in with my other characters fine. Do not tell me it is due to an addon i may have, seeing as I do not download any. I checked my internet connection, it is fine, this is why I can log into my other characters Etc. Anyway, thanks.
