hello can somebody help with atc problem

just installed fs 2004 on vista ultimate 32 bit (express install)
game runs okay, except no atc, the atc menu comes up asking to choose option, tower or ground etc, but clicking any option with mouse
nothing happens? menu seems dead, tried different planes/flights, enabled settings for atc
still the same, uninstalled and reinstalled still atc menu not working,
have had fsx on this machine previousley(now uninstalled) and atc worked fine.
I have searched high and low in vain for a solution, just hoping some of you kind people can help
