Yeah like I said before
Only Legit way to get a fully working copy of Ds2 or Ds3 is from Contacting Tech Support.
Ask for Craig or dang it I forgot her name, chick that helped me out a few months ago. I think it was Ashley. They will be more than happy to help you out. As agents they have copies of almost all previous versions of the Studio Installers.
They will either send it to you via email or reset it from your itemized order history.
They were able to get me Version 188.8.131.52. which I believe was the last FF official release.
I also have 184.108.40.206
I also still have the installer for my first version of studio which was 1.8
