Unfortunately, I don't have the same problem - no channels mapped to a group that no longer exists. I've attached a SQL backup of my database (using MS SQL 2005 Express).
What happened on my system:
1. Installed 1.0.0 on a clean Vista SP1 box. Everything fine, TV Group tabs available.
2. When it became available, installed 1.0.1 using the update option. TV Group tabs gone.
3. When it became available, installed 1.0.2 using the update option. TV Group tabs still gone.
I would really prefer a solution that doesn't involve dropping the database and redoing the config, since that would mean a lot of work...

edit: TVServer logs attached, too.
