Failure - Trying to Back up MS Streets & Trips 2003

[Pavel]

I am trying to back this program (two cds) to CDRW using my Plextor 8432 writer. I was only able to back-up disk 2. Setup Disk 1 wouldnt even register in Explorer. I am using the latest Clone CD.

Any advice or recommendations on a program that will allow me to back up?

Thanks
