IR does not Connect to Uwatec dive computer

The usbuirt device is my firsst IR device. It appears to have the drivers installed correctly on both my laptop and tower PC, but I don't know how to tell if it is "on". And the dive computer aoftware states it cannnot find the "usbuirt" device. Can there be a frequency problem or may be I set the dive computer too close to the transmitter - emitter?Any suggestions would be appreciated.
Am running Windows 7 (32 bit on lPTOP and 64 bit on PC tower.)Dive computer is a Galilieo Luna.
