All of those scripts were written in Python 2.x. It is now a deprecated language version and Poser 12 uses Python 3.x. And yes, that means basically everything we had before is not useless.

The good news is that there is work behind the scenes to fix some of the major ones. The bad news is: as to scripts we purchased for money here before--I'd suggest to contact the vendor and see if they have plans to redo those. When they were released, they worked, but as always, there is never a guarantee that older products would work in newer software versions. It sucks, but I remember when a lot of scripts stopped working when PP12 came out as well.

I hope the store plans to clearly mark the older scripts as to in what version of Poser they work in.
