Probably: but, yet again, that's from the RStudio people, which is a
completely different and entirely autonomous organization. I would
like to help you, but the recovery process may well be quite sensitive
and you'll need to check with them to make sure a re-install doesn't
clobber saved user state.

Also: moral of this story =  Save your files in a user directory
instead of trusting a convenience feature and backup!
