Production Assistant version 1.0

I recently had to wipe my hard drive & reinstall windows 7 on my computer. I was running Vegas Pro 9 & Production Assistant 1.0. I saved everything before the reinstall but cannot get production assistant to load and cannot find a site that will allow to download the old version (which done all I needed to do). I purchased this online & have the key but no physical disc. Would you please advise on what I can do to get this back.
Thanks Ron
