Bondware is the owner of Poser now, and as far as I know the older versions of Poser released before they took over in 2019 were not transferred over to them. They were the property of Smith Micro, who no longer owns or supports the older versions.

Poser Pro 2010 is now 14 years old and content compatibility would be limited at this point in time. Have you looked into upgrading Poser?  It's come a long way since then.
