How to make a copy of Traffic Giant

[eekdefret]

fDoes somebody know how to make a copy of Traffic Giant.
The CD contains 3 tracks and the second track is a audio track.
All the files in the first and third track are about 600 MB.
Making a ISO with Nero 5.0.1.8 doesn't work.
Starting the burning of the imagefile results in several errors like "illegal contains of file"

Please Help.
