You can snag a copy (with valid member access) at the member area link at the top of every page.
The issue, as it seems, is that ultimatebb.com wasn't sold to Rick (and by relation UBB Systems) when Groupee split out of the picture, it looks like the hardcoded member area link was never updated in the licensing software.
