Installation problem

Help!
Hi All,
My laptop runs XP and is set up with an Admin account and a limited User account. I load all software using the Admin account so I loaded Notion 3 and the two Plug-Ins supplied, and registered them. In the Admin account everything worked and I had a good play with it to test it.
When I eventually switched to the User account Notion reported it could not find the plug-ins. I contacted Notion who told me to create a folder C\Programs\Steinberger\VstPlugins and reload the plug-ins into it. I did this and it had no effect. So I used Windows to remove the whole Notion 3 set-up intending to reload it in the User account, reasoning that it would then work in that account and it didn't matter if it didn't work in the Admin account. However Windows cannot now find anything on the installation DVD #1: it's as though it's blank. DVD#2 is fine. What's going on?
(I've contacted the same guy who suggested the fix but he's probably off for the weekend now)
