We can't help you with that message. For some reason, they aren't liking the account you created. You'll need to use the link in that post to submit an appeal to them and may need to verify you are who you say are when you created the Facebook profile. We can't work around their security checks in any way, and what you're running into is a security check.
Usually, the submission of that form is a pretty quick process and (from my understanding), accounts can be verified and allowed (if your information is legitimate) in 1-3 days. So, all I can suggest is starting down that path.
The only other alternative is to use a friends account to create your Facebook Application. They can do it immediately and then add you as an administrator at a later date. You can then remove them as an administrator as well. It's a roundabout way, but if you need to get up and running now, you'll need some sort of account to create the Facebook Application.
Finally, there are some features of JFBConnect that don't require an Application at all. Most features do need it, but things like Like buttons and Comment boxes can be automatically inserted into your content right now without one. If you need Login functionality, Facebook Invites/Requests, or other advanced features, that *will* require an application to be created.
Hope that helps, and sorry for the troubles,
Alex
