Not responding

[Ráge]

Can some one advise me on what to do...

Every time i log in on my main Toon i get the message

World of war craft is not responding last for a few mins and finally i get in
but this seems to happen on every loading screen ?

Note my main is the only one with this problem my two other chars are unaffected by this !

Yes i have tried the repair tool as well as Re-installing the game...

Thanks in advance !
