Need Original CD in Drive message, Backup Copy Doesn't Work

[YIRMASTER]

I successfully burned a copy of the cd but when I put the new copy in the drive to test that it works I get a message that says: "This program cannot run without the original CD in the drive." How do I get around this copy protection? A backup copy is useless if it dont work.

I am trying to make a copy of:
ISBN# 0-7931-9370-2
Questions& Answers - Software to Help You Pass the Real Estate Exam

My Drive is:
LITE-ON DVDRW SHW-1635S
Driver: 5.1.2535.0

Any help, please!
