I'm on the EU, I just realized this.. LOL

I'm normally playing on the US but I'm playing on EU for the first time in a long time to play with some overseas friends. How would I change the realmlist to EU not US?

This is the error that I'm getting.

Problem with oQueue - Help please!

I've installed oQueue by downloading the zip file and extracting it to wow/interface/addons and from there I went to play and it shows up in my addons list but it does not work in game for some reason.



When I am in game I get no button near my map to press and if I type /oqueue all I get is this screen. 




Here is another picture of my addons screen in game.




Any help would be appreciated as I recently returned to WoW after a small break and it's hard for me to play without oQueue.
