I'm also running Blacksmith 5. The interface sucks compared to new versions, and I actually bought a newer version, but I'm not going to support software that dies.

I have limited choice with Poser, however, because of all the models purchased over the years, unless I go DAZ. And that would mess up poser scenes and other things with Poser that I've made over time. Either way, because of the darned kill switch I now face a significant time sink just to get back to where I was three days ago. I lose because I chose Poser over Daz originally.
