79389 Fix php autosurf script, easy

I have purchased a php auto surf script (phptraffic script v.1.0) I have the script already installed but have run into a couple of issues. The script will not let me into the admin area as per the instructions that came with the script. I have followed the instructions to the T and when entering the username and password provided in the script to enter, nothing happens. The username and pass screens clear and I am not taken to the admin area. I need this resolved... please let me know your ideas, I need someone to fix this very quickly,...should be an easy fix for a skilled programmer. thanks -
