Export projects from HBPM beta

I finally got around to trying to export my projects from the history-based parametric modeling beta version to the release version, and I can no longer open the beta version. TestFlight says there are still 11 days left, which agrees with this thread that says it should continue to work for about 90 days. I see two errors when I try to open it.

Is there anything I can do to recover these projects?
