Delta Force 3 Land Warrior

[greyzone]

How do I copy land warrior? disk juggler doesn't work, clone cd,nero,cdr win, all are no go...I did notice that two files (Terrains.pff and Dflw.pff) both say that they are 2 or 2 1/2MB each, and after copying the rest to the hard drive and faking them, nothing would run... guess the textures for the game are in terrains.pff, and the other info in Dflw.pff, loading with an empty file is instantaneous,and is a lot slower than the original...I really need to back this up though, as I have gone through 3 backup copies of DF2 (LAN party damage) and here in germany the original american version has cost me approx. 70 dollars!!!! Please Help if you can!!!
My burner is a Teac 55s, and I have access to a mitsumi with clone cd capabilities.... Thanks in advance;-))
