WMP Problems

Question

First: I'm running XP Pro, and have WMP 9 Series. My Problem: I have a program that uses the WMP control. This program workes fine when run on this computer. However, when I run it on a different pc (Win XP Home & WMP 9 Series), the program won't even start. Any suggestions?? Thanks! P.S. I have narrowed the problem down to the wmp control.
