I am new to Windows XP Pro, but I bought it with my new computer.

I have a gameshark for a video game system that can plug in to the parallel port on a computer. I downloaded the required software, but it says it only works with Windows 95/98 and ME. So I plugged it in, and I changed the compatibility mode to Windows 98/ME, and selected "turn off advanced text services.." and "disable visual themes."

So, the program starts up ok, but it cannot communicate to it through the parallel port (it says it doesn't respond). Now I am running this program under my userame which is the administrator, but I am wondering if there is anything else in XP Pro I need to enable in order for this to work...
