Hello and welcome to the forums

I have used MB3D on Win8, but refuse to update to 8.1 (I never allow any updates to my computers). I only wound up with 8 due to bad circumstances too, would rather have skipped it, but ... didn't).
I saw your other post and that is a strange issue indeed. I can only say it works on 8.0
Hopefully somebody else will have an answer for you.
Enjoy the site, and feel free to post some of your stuff here (many of us don't bother visiting external links because we're a lazy bunch!).
