Before you bother with trying to get that working, I would check with your web hosting provider to see if they already have a database front end.
Usually, they have a link to it in the "control panel" for your domain, if they offer that. Or, in their customer service, you might dig up a link to what they have configured.
If for some reason that doesn't lead anywhere, then I'll see if I can help... though I've not used the front end you mentioned and I would only be able to offer wild guesses about the trouble you are having.
