I have a DAVE project with about forty DAVE apps and perhaps a hundred or so C source files.

Suddenly, whenever I would launch DAVE, it would error "Problem occurred while restoring the project data. The project 'MYPROJECTNAME' is not usable any more.

After launch, there are about 12 errors in the "Problems" tab of the form: "Groovy object not found for (MY NAME FOR A DAVE APP)". I can still work with the source of my project (thank goodness). I can still compile, but all DAPP side things are broken.

Is there a way to fix this project?
