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

1.8.6b not working for some reason

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?
