WotLK Stuck in Dungeon Finder party, alone...

[Pithikotsis99]

So i queued earlier for a random heroic dungeon, we killed last boss and everyone left the party and i ended up alone so i tp out. Then I tried to queue for another dungeon but it popped the party role selection and eventually cancelled my queue because "another group member did not respond" but no one is in my group but me. No leave party option is available and I can't invite other players or queue again because of "internal LFG error". Please help.

*Edit: Also there is another message when i try to queue "One or more party members are pending invites or disconnected"
