Multiplicity 1.02b not working with Windows 7

One of my workstations was recently upgraded to Windows 7. Befor I had two workstations running Windows XP pro SP3 and Multipilicity 1.02b worked with them. Sine upgrading the secondary workstation to Windows 7 Enterpise SP1 Multiplicity 102b does not work, I can switch between workstations by double tapping the scrool lok key, but htats all. Is Multipilicity 1.02b work with Windows 7 or do I need to upgrade. If Mulitipilicy 1.02b works with Windows 7 what is the fix?
