Thanks, robert_e_bone. That's definitely a good suggestion, but doesn't apply in this case. I'm aware how UAC works. I'm in IT and actually have a domain set up at my house. lol. :-)
OK, so reinstalling everything worked. In fact, it didn't even ask me to register this time (installing all from Command Center). I can't explain it. Maybe I fat fingered a serial number along the way or maybe microapp was right and I copied an older serial from the Project 5 days in my haze of mass product upgrade/installation.
So I'm good now. Still upset that Cake isn't replying to week+ old tickets, but at least the forums are active! :-)
