6.0.3 upgrade not working

Upgraded to 6.0.3, my machine running vista. Now if I try to open database says "Serial number missing. Re-install Act. Any ideas on a fix?

Re: 6.0.3 upgrade not working

ACT! 6.0 was never designed to work with Windows Vista.


You could try disabling UAC on Vista... if that doesn't work, then uninstall and reinstall ACT! 6
