Which may be connected...?

1) Logitech profiler doesn't appear to be working - I've applied a
persistent profile including button 5 for shift+t to reset the tach but it's
not being picked up.

2) Game controller utility under XP will happily report a combined axis for
pedals correctly, but not separate. When switching mode to separate axis for
brake & throttle the two needles on the properties screen report full
depression and won't budge. Have tried using the Logitech ClrCalib utility
and searched their knowledge base to no avail.

3) When launching GEM+ 2.2.1 it has suddenly started trying to install
GPLAIM and searching (unsuccessfully) for 'gplaim.msi'. Not sure what's
going on here at all.

I'm presuming all of this is related to a recent upgrade of m/b, cpu and
video card. General specs are as follows:

P4 3GHz
512mb RAM
Excalibur 9800Pro
Audigy2
Win XP (Home)

If anyone's got any suggestions at all I'd be very grateful.

Thanks for reading this far!
Regards,
Rick.
