Just updated to version 1.8.4f and when I open in game there is nothing available. The priv. versions worked great.

Having the same problem here, cant see anything open =/ 

As am I, no premades are popping up, I even tried creating my own but to no avail, halp! :(

look top left, what are the numbers next to 'premades'?  if its something like '(0 - 200)' then you have premades, they're just not showing due to your filter rules.  clicking 'clear filters' should clear them all and result in '(200 - 200)' premades showing

if you have '(0 - 0)' then you're not receiving the I formation.  check your connection in the lower right.  if those two numbers addto less then 20, your connection is weak.  try hitting 'find mesh'.  

Same problem here, 0-0. It's simply not sending/receiving any friend requests on clicking find mesh, but it does connect to other users on my realm (which isn't enough). OQ worked flawlessly for many moons, until yesterday. :(

Make sure you delete your old oqueue folder, and move in the newly extracted one to your addons folder
