Losing Abyssal ID after Error

I just tried to join a Abyssal Raid with my friends, but we all now. Because of the current server status its rly difficult. Still we joined one and succeded to get into the dungeon. We assumed actualy, but after the dungeon loading screen we got kicked out again.
We tried to join again but we couldnt, because we lost our ID for the Dungeon.

This is a big problem since all following Abyssal Raids depend on the completion of this one, which we now cant do!
