The VN mod in the downloads/mods section is old, you need v2.0.
Go to
http://www.freewebs.com/dgvnmods/mods.htm
At the bottom of the page after "SPECIAL NOTE>>>> Balanced scn's in.." you will find 19 files.
File 17 is the install instructions but is a bit out of date. Disregard "Blitz FTP" and use the 19 files you got..
Note that some zip files contains folder names that are not used. Such as DGARVN2.00, DGBRITT2.00.. so be sure to uncheck 'Use folder names' in winzip. Unless it is something that goes into the PICTURES folder which is used..
Also note that the Blitz FTP has v2.01 of some OOBs. Not necessary though..
