wireless connect problems

hi,
for about 2 years I had a microsoft wireless connect
between 2 computers, both had windows 98. base station a
pentium 3 and external station a pentium 2. I upgraded to
XP on my base station and everything was still fine...
Reciently I purchased a pentium 4 with XP to replace the
pentium 2 but now when I install the remote receiver and
install the software it doesn't work... ant ideas? Do you
think it is beceauce the base station is a 3 and the
remote station is a 4?

please e-mail me direct >(E-Mail Removed)< if you
have an answer, many thanks

Dave
