WotLK disconnect when logging in on specific characters

[Swordman]

I have a problem logging in on certain characters on my laptop, but on my desktop I don't have the problem. I can log into my other characters but, my main character at the top of my list, disconnects from the server when I try to log on it. The message that pops up simply says "You have been disconnected from the server"

try to disable all of your addons.

Btw what Class and what lvl is that character?

I'll try that. Level 80 Priest
