Gran Turismo backup doesn't work

vbimport

#1

I backupped the cd from a already copied Gran Turismo as descriped on Gamecopyworld with cdrwin.
The original copy has several files but mine has just one big audio file.
I used a philips Silver Premium CDR with green dye color and my burner is a Traxdate 2260+.
Does anyone know what my problem might be
