Hey,
I just downloaded and installed oQueue (not the first time i install addons manually, i have done that for 6 years until i started using clients so im sure i did it right) 
When i login to the game, i get ping errors for all my friends (see screenshot) and when i open oqueue using /oq the window is just black and empty... (see screenshot) 
I never had this with any addon...

Currently residing on Vent in Room 0 dev & support, hoping someone will log on...

5am is a rough time for support.
as for the screenshots, they didn't seem to work in the post.
I'm not sure what 'ping errors' would mean.

try disabling all addons except oQueue and logging in.  when you first lg in, check the general chat area for any error messages

V3lv3t,

When that happens it normally means that you have the adddon installed incorrectly (ie: files are missing). I would suggest deleting oQueue from your /addons folder, then doing a fresh install. 

This can also happen when someone has previously played on a private server, and they have messed up their realm list. 

The version xxx at the top center of the addon is a clear sign that it did not "install" correctly. Even though installing the addon really only means unzipping the zip file in the correct location. Also make sure you only get oQueue here on Solidice.com to ensure you have a valid copy. 

Oh, i guess your forums show the time on my computer hehe. Well i stayed there for about 4 hours after i posted ;)

Ronburgundy, first time i extraced directly to the interface folder.
Then i deleted everything, downloaded it again, and extracted to the download folder, then copied to the interface folder.
I also haven't played on a private server the last 5 years, and since then my pc and wow have been reinstalled numerous times.
I also downloaded straight from this website not from anywhere else.

And for the record i just tried again, nothing changed, not even with every other addon disabled.
