I could not get 1.8.5 to work either. The last version that worked fine for me was 1.8.4f.

When i type /oqueue the window comes up but shows nothing and says vx.xx in the title window. Is there something else you have to do after you extract the files into your addon folder?

Hey something is wrong with the realmlist. i have the same problem
Just w8ing for tiny to respond
 

I managed to get it to work in the end i think there might have been an extraction error 

You can try doing the following:

/oq harddrop
/reloadui

If that doesn't work, you will want to make sure your realm list is set properly. If you are connecting to EU, and you are a US player, or vise versa, the addon will not load properly.
