One of my tests in Quality Center is not generating a QTP script. It fails with the error "Another loading action is performing"

This has been occuring for the same test (and other tests of the same name in different folders) for a few days now, although I can generate scripts for dozens of other tests.

There is no "lock" in the database that I can find. This is on QC with QTP 9.5.

Is there some way to fix this?
