Are you sure it is the right manual? I couldn't find any place to download it from MTU.
You do have 3.4 as long as 4.02 is installed. Look in
C:\Program Files\Micro Technologies Unlimited\Hoster for a file called Hoster34.exe. Right click on it and Send To Desktop(as shortcut). Then you can use it from there. It is 3.321 updated to use the version 4 registration.
Do you know what video card you have and how much memory it has? Also how much memory do you have in the computer? Both of these could effect the import. I have seen some problems with importing, but not causing interference with singers. We have always kept our CDG player in the rack just in case and it doesn't add much weight to it.
