2.0.7 update - DT can no longer load database

After downloading the latest update, Devonthink is having problems: it hangs when trying to initialize one of my 2 databases, so I can’t get into DT at all right now. What do I do?

Seems ok now: cancelling the attempted opening of the databases allowed me to get into DT with nothing open; opening the databases from there seemed to go OK; my global inbox had disappeared, but managed to reconstitute it following the instructions in the FAQs.
