Windows vs. Unix - script incompatibilities?

I'm currently running PHP 4.3.6 on a Windows 2000 Advanced Server SP4 box with IIS 5.0 and MySQL 4.0.18. I was able to install everything ok and have phpMyAdmin running to admin the MySQL database (that script is a godsend!). The problem I'm having is with a 3rd party PHP address book script that I'm trying to run and configure by Liqua Web Solutions called WBContacts. I have been able to install, configure, and admin this script fine on a Unix test box, but have been unsuccessful so far in getting it to run successfully in a Windows environment. I've contacted the script's author and he's being a big help in trying to help me get this up and running, but I was wondering if anyone here has run into this kind of thing before?
