Hmmm.  Are you pasting it in or typing it?  If pasting look for trailing spaces.  If typing it, IIRC there are no 'i's nor 'o's, but they are ones and zeros.  Also, you may need to be connected to the Internet when entering it.

Since I first bought Poser 7, I've always bought the upgrade, but have never needed the previous serial.

File a support ticket if you entered it correctly...
