I just downloaded better bodies and it shows up as an installer, but when I try to run the program it sends me an error message that says: The setup files are corrupted. Please obtain a new copy of the program. But no matter how many times I download it ir which source I get it from, the same message shows. Has anyone else had this problem, and can anyone help me?

Where did you get the archive? I believe it's still available directly from the psychodog studios site, and it was working at least a few months ago.
