[ANSWERED]I cant look Dungeon - BUG?

Yesterday after leaving the group because the other player retired earlier, try to find a group for dungeon again.
The problem starts here, because the game tells me that i am in a group, when i really am not and when a invite a group to other character it tells me that "it is not in your instance"
The option to "leave the group" does not appear to me either because i'm not.
Try to connect again, close the game, send a group of some friends and nothings.
This is what it tells me when i search for a random dungeon: "One or more party members are pending invites or disconnected"

Please Help =(
