DOORS Next Gen: Getting Project In Use Message

I signed on after several months of inactivity.  I was waiting for the sandbox upgrade to finish.  I selected DOORS Next Gen. and then selected to initialize my project.  The thing hung in that state for a long time and I gave up.

A few days later, I signed in again and I get a message saying my project is in use.  How do I free up my project?  If I try to create a different project, it will just tell me I get only one project.
