Bunch of data disappeared from db but still present on disk

That protocol seems to be broken, though:
When I startup Brainstorm with that protocol loaded, the tree shows "Loading..." for a while, then nothing anymore:

Until I click on the "anatomy" tab, and back.

How can I rescue that protocol?
As you may guess, this bug appeared after that previous issue we talked about here.

Many thanks,
