Sorry, it posted my message before I was done! Yes, it is possible to use 2.0d with DX7 - at least if you are
using Vegas primarily for audio. I understand that you need DX8 for some of the video stuff. I'm not doing video
so I used DXBuster to remove the 'orrible DX8 and then installed DX7 and since then 2.0d has been working
perfectly and I have all my plug-ins back (they disappeared with DX8).
