Ever since I purchased Standard Pro Drumset, my Beatbuddy Manager is a mess!?!

I uploaded Standard Pro and it works good, but now - no other drum set works. In fact, when I go to click on any pre loaded drum beats, (Say, Blues 1 or Rock 1) the software shuts down. I’ve tried reloading (importing) all the drum sets. If I switch the drumset to Standard Pro, it works. ( I have the latest firmware & manager updates)

It sounds like your BBWorkspace may have become corrupted. Try the Disaster recovery procedure that Persist posted last week, I believe.
