It is not necsarry to be a PHP exxpert to get the solution pack working.
GoDaddy is notoriously difficult with sending emails using the PHP mail() function. DO a google search for "godaddy php email script" and you will find tons of evidence of people having difficulties sending emails using GoDaddy:
In a few threads I found reference to the version of PHP, It seams they do not enable the mail() function in PHP 4, you need to request PHP 5 hosting to for the mail() function to work. If you are still having problems, contact GoDaddy support and ask them if sending emails using the PHP mail() function is supported on your hosting account just to make sure.
