Fix reminder script

This is a very simple project so I would expect a very low bid to be the one I select. This could just be (and probably is) just a matter of fixing the cron job for this script. Here is the situation. I have a script that is commonly found available at hundreds of sites selling the "Master Resale Rights" and "Resale Rights" scripts. It is a reminder script. I bought mine from a seller on eBay as a master resale rights script. I will of course also give a copy to whoever fixes it and they can also feel free to resale it as modify it and resale it as needed. I have it installed, I am sure I have the script setup and installed properly, the only thing I feel unsure about is the cron job. But since I do not know what the problem is it could be anything. The problem is, obvioulsy, that the reminder function is not working. The script is supposed to allow visitors to signup for an account, and enter dates and times on the calendar. The script is then supposed to email the visitor of the scheduled event the customer has setup on the calendar. I have yet to get it to send the correct date even once. I am pretty certain it is just the cron job that is the problem. The site I have the script on is [login to view URL] but it has been heavily customized so you mya not recognize the script if you are familiar with all of the resale scripts floating around out there. Here is a link to a site with the script in its out-of-the-box look [login to view URL] I will pay to GAF escrow in the providers name upon begining of the project and will release funds when the script has been fixed and is working.
