Does the program work OK if you run it in a Windows XP compatibility mode? If you haven't tried that, give that a try. Most programs that run in XP will run in Native Win 7, but there are some exceptions and for those you need to run in a Compatibility mode.
Some also require running as Administrator (even though your log on has Adminstrator rights). To do this RIGHT click on the icon for the program and then LEFT click Run as Administrator.
