How do I make an image of Swat 3 Elite Edition???

Hi everyone!
I just bought Swat 3 Elite Edition US version and I wanna make backups so my daughters won't mess them up:-) When I tried to make an image of the disk, my CD reader (Toshiba 6205 I think) just spins and my CDRWIN says that errors occur. This also happens when I try to make an image w/ my CD-Writer (HP 8110i). Please help!
