My character 40 level Priest Stuck in a group

hello:

My character a 40 level priest stuck in a group when I queued Random Dungeon.
When I queued that dungeon, it didn't let us (all team member) teleport to the dungeon, says "instance full".
Then everyone else left the group.
Now I do not have any party member but I cannot queue for dungeon, cannot invite people, cannot be invited.
I tried log out, completely restart the game, and looking for help in the guild but they haven't seen this issue before.
Can you help me look into this issue?

Thanks.

Type this in.

THANK YOU AND THANK GOD. I was so scared that my character was stuck.
