Problem Installing Scriptcase

I am attempting to install scriptcase on hostgator and running into a problem. Although all required packages are installed, i get the below error. Can anyone provide some insight into what i have done wrong.

Fatal error: SourceGuardian Loader - Protected script’s header is broken. Probably the encoded file was modified. Please install an original unmodified file or contact the author of the script to get the original file. Error code [10] in public_html/scriptcasedesigner/devel/iface/login.php on line 2

Bump… Nobody has ever seen this?

May you post what is the version of the PHP and the SourceGuardian installed?
