Trust me, you're not a pain. There are a couple others here that really are a pain right now. You're simply someone who I can help. I hope you get it sorted out. DM 4.2.1 SP1 will work with Vista. However, if the procedure above doesn't work with Vista then you'll need to find an XP machine. I know it will work on that. I can only assume the registry entries are the same for Vista. If not, you'll be out of luck until you find an XP machine or someone can give instructions for Vista.
