The OP never said they upgraded from a previous version.

To PJBear: You only have the SN on the box/CD, right? Not in any form where you can just copy/paste it?

You won't need the dashes.

I just re-entered my Poser 8 serial - (for some reason it didn't survive my latest migration to a new computer and I had to track my order at SmithMicro to find it again L*)

My serial number has 7-4-4-4-4 in the format of

AA11AAA-1111-11AA-AAA1-AAA1

where A denotes a letter and 1 a number. hope that helps. And for the record, I couldn't type in the "previous serial number field although mine was an upgrade from Poser 7. It still registred fine.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
