Ok..so, have finally gotten the computer to recognize the dongle...thanks to an hour phone call with Microsoft. As for blaming SP2, Microsoft said they find it suprising this issue is only now cropping up since the beta version was available for software providers to test for more than 1 year. So, anyway you cut it, this is a problem for Vectorworks..and I hope you appreciate that it makes your software unuseable and that this type of snafu is a potential PR coup for your competitors. In addition, telling us to wait patiently is unacceptable in light of Microsoft's comments.
