I looked at your site, and it seems everything is installed correctly. Maybe you have found the problem.
The most common problem with login errors are because the user's browser is blocking cookies. This does not seem to be the issue.
It looks like all parts of the installation query before and after adding the login information were processed correctly.
It would be quite strange to miss one query in the middle of that process.

If you have not solved the problem, try running the following query directly on the database. Use your specified database prefix if you changed 'sos_', and use your own email address.
INSERT INTO `sos_hw_admin` VALUES (1, 'demo', 'youremail@northjerseyhosting.com', 'fe01ce2a7fbac8fafaed7c982a04e229', '', '', '2007-07-22 20:58:54')OR
Reinstall.
If you don't know how to write directly to the database, reply, and I'll write you a file that will do it.
