Well... I'm still waiting for AC to respond to my problem. Is there just one programmer working for them? In any case, I decided to move forward, again, to start using the software and today discovered that the same problem happens with MS Outlook. When ever I try to add a new contact the MS Ultimate 2007 setup screen appears. Very annoying. It appears I may have to choose between office 2007 and AC. Is anyone out there using Office 2007 with AC? Having problems??
