If you can cancel your order or return it, do it.  Poser 9 is better.

Also, Amazon typically has Smith Micro products as "lightning deals" at this time of year.  You might want to wait a bit and see if Poser 9 or 2012 is featured.  Last year they had Poser 9 for $59.95, and Poser Pro 2012 for $120.99.  Dunno if they'll do it this year, but it probably won't hurt to wait.  There are usually good bargains on software available around Christmas.
