The document I linked to details how to copy games. The error messege you received is because of the Safedisk 2.51 protection.
Your burner must be capable of perfect EFM coding (see
here and see if your burner has two sheep in the EFM column). If it has then use Clone CD to copy the game but disable AWS. When playing the game, if you play from a burner, enable Hide CD-R Media to get around the ATIP check (search for more detailed explanation).
If it has one sheep, then enable AWS, but it is not guarateed to copy sucessfully, but will do in most cases.
If no sheep, then you have little hope of a 1:1 copy so you should download a crack from one of the sites listed in the sticky topic.
That's the basics of copying the game. More detailed info cannot be given as you haven't given detailed informatio - cd-writer, Clone CD settings etc
All of this information could have be obtained by reading the FAQ
