MCE 2005 doesn't see USB-UIRT

Hello, I'm hoping someone here can help me with this. I recently bought some hardware to build a Media Center 2005 machine. I installed MCE, and my USB-UIRT, when I run through the TV setup it finds my Hauppauge winTV tuner just fine but after telling MCE that I have a set top box it scans for IR hardware to control the set top box (satelite receiver) and says "No IR hardware detected" my USB-UIRT is listed in device manager and was sure I could use it to control my set top box, am I wrong? Is there something else i need to do, maybe some software I am missing?
