Creating multisession cd in cdrwin



I am trying to copy Half Life Opposing Force ( 1 data 19 audio tracks)using the patch from gamecopyworld.

I can extract all the tracks and create the data track but everytime I try to write the audio tracks, I get a write error. Anyone know how to create these multisession cds in cdrwin. I like the program and I know Nero is easier. Many thanks.
