Carpet Rover Comms

Hi there,
I have an old Carpet Rover that I like to restore to life, but I am having problem with uploading the Basic Program to it.
I am using the Parrallel Port and Window XP
It keeps telling me that it is unable to find hardware.
I am using Stamp.exe and Stamp 1.4 Chip
It has worked in the past , but was on Win 98 and another Pc

Any help would be most appreciated
