installed a downloaded script possible database problem

hi all,
I have recently downloaded a script from cobrascripts. It is called autohits
I have tried contacting cobrascripts but as it is a free script they are not interested in helping. So I am hoping someone here will help me. I have done as they said,
Installed script
Installed database table
and it works to some degree ie I have created a fake account and managed to login as a regular user.
The problem is I can not access the admin area with the username and password they have given me.
Is there away around this ?
When I login to phpMyAdmin there is no user listed there called admin, so I created a user called "admin" and gave it the password "test" but it still did not work. I'm not sure if that is because I have created the user inaccurately or not. As my phpMyAdmin skills are not as good as I would like.
Can anyone help me get this up and running ie point my nose in the right direction.
I was going to post a link with a username and password but the forum wont let me.

I worked on the assumption that if one can create a user account then I have installed the table correctly. So now you have it why cant I login to admin panel


Regards Nige.

I would be looking between the error logs and php code to determine if the script is actually working and doing it's job.
