Blacksmith3D?

I tried the demo for a retexture I'm trying to make and it worked beautifully, but the demo doesn't let you save projects. So I downloaded what claimed to be a full copy, which is just the same thing plus what I assume is a registration code, but it still requires a valid email to use. So I'm wondering if a cracked version exists, or something that can do the same things that doesn't cost so much? Or even someone who has the full version and would be willing to make a quick thing for me for points?
