I don't have my purchased copy Poser 11 pro backed up externally because I assumed, silly me, that any item in my purchase library would be archived. So now when I change computers I guess I'll no longer have the option of installing 11 pro on my new machine? Even though I have purchased Poser 13 I'd still like to have 11 pro for my Python scripts (and no the functionality of these particular scripts have NOT been replaced by what's available for 13).

So it's still for sale but not downloadable? I'm confused.

So if this is the case the monies I paid out for Poser 11 a few years ago was simply an undeclared rental?

I'm giving the benefit of the doubt here.
