Supporter has stopped working

My supporter plugin seems fine and I can except payments through paypal, but blogs don't get upgraded.

At times members blogs also get set to subscribers instead of admins. From what I can tell this happens on new blogs, not from older blogs when members only upgrade later.

From what I can recall this also started to happen before my upgrade.

Not sure if my previous database problems from this thread have anything to do with it, but doubt it.

These are the tables I have in Multi-DB..

#Supporter tables
add_global_table('supporters');
add_global_table('supporter_ads');
add_global_table('supporter_transactions');
add_global_table('supporter_faq');
add_global_table('supporter_faq_cats');
add_global_table('supporter_tickets');
add_global_table('supporter_tickets_cats');
add_global_table('supporter_tickets_messages');
#add_global_table('supporter_signup_stats');
#add_global_table('supporter_daily_stats');

I have the latest Multi-DB, supporter, buddypress 1.2.2.1 and wpmu 2.9.2

Any idea what could be wrong?
