message inscreen

Goodevening Community,

20 minutes ago i queued for wintergrasp and i had to wait 5 minutes for it to begin, i got called away from my computer and missed the start of wintergrasp. When i came back a message appeared inscreen: http://imgur.com/g1AOwS9
I can click the message but it only dissapears for 0.5 seconds and then it is back. The following things i tried:

i did /reload, i exited wow and started over again and i used another 3.3.5 client.
Allso i tried to leave dalaran and go to another place in kalimdor.
The game at the moment is hard to play with a big message in the middle of the screen
Hope someone can help me
