Scrivener can't backup

Hi everyone,

I’m not able to make backups. Whenever I try, I get a “Could not create file” or “Could not create project” error.

I’ve tested a number of different directories and configurations, but nothing seems to do the trick.

I did a lot of work tonight and I hope to save it.

Looking for advice.


P.S. The top post here has the identical problem, but I don’t see a fix or resolution:

FYI: Using Windows 7, running version 1.9
