User Sign-Up not working for Directory plug-in

When a person clicks the "Sign-Up" button, they are instantly taken to a page with the following message:

"Signup ( complete ) The registration is completed successfully! You can go to your profile and review/change your personal information, or you can go straight to the directory listing submission page."

Clicking on the Profile link just takes them to the login page, for which they do not have a login.

The directory was installed with the standard theme that came with the plugin. Let me know if you would like the link.

Other than this and one other question (submitted separately), the directly seems to be working well.

Thanks in advance for your help!
