Many people have had the same response, and it bears repeating.
Why have a free version if you can't use it? You can install it but you can't see whether it correctly returns entries? Silly. I already saw that Formidable employees try to move the conversation to their site whenever you comment.
Once you get to the site, they tell it's very hard to view entries. Formidable wasn't designed for that.
Frustrating free version that shouldn't be offered at all without proper documentation. I would have even been willing to buy it instead of Gravity, if it worked. You don't have to give away all your bells and whistles, but it should work.
This FREE version is a waste of time. Don't bother.
