It's not about functionality. I don't need the additional features Infinite has over the Complete version.

All I want is to be able to USE THE CONTENT I HAVE ALREADY PAID FOR.

I don't want any new plants, so I don't see why I should be forced to pay again to get the same files which I already have. It's only a matter of registration, after all.

Could you imagine having to re-purchase all your Poser content after you switched to a different version?
