BBM Group recovery

Hey all. I just made the switch and for some reason only 2 of the 3 BBM groups I have shows up in my list. I still have my 9700 so brought up the group bar code from there, scanned it, but is says that I'm already part of the group. Does anyone have any suggestions on how to make it show or rejoin?

In case anyone from the group reads this, it's the "Former NYC BB10 Launch Group" I got a coffee brought at the store this morning while waiting in line for my Z10 by one of the members.

One of the group members should see you as unreachable, and an admin can send you an invite to rejoin. You don't have one member on your BBM?
