There is no link on the login page for signing up. It's something that was left out of the script. It should be fixed in the next release.
Go to http://www.jpdeni.com/dbman/Mods/bugfix.txt and scroll down to the bottom of the page. You'll see a replacement for the login form. Paste that into your html.pl file and you should be all right.
You can check the .pass file and change the entry there. It should look something like
admin:A.f0Kvdiyy8q2:1:1:1:1:1
with a 1 at the end. If it ends with a :, add a 1 to the end of the line. If it ends with a 0, change it to a 1.
