Same problem here with the serial numbers. I believe I was one of the first people on the planet to buy Bryce 4 (man those were the days ... I was actually MASSIVELY EXCITED about a Metacreations upgrade!) so naturally I have a Meta version. The frustrating thing is by the time I get done putting the three kids to bed and have some time check it out, Corel is of course closed. So I'll have to call tomorrow. I'm glad I got NextDay shipping for free, or I'd be really peeved I wasted two days. ;-) -Tim
