crazy taxi backup doesn't boot

[Ç!i!]

Thanks again all

Just another question..... Should i copy using cd to cd or should i do it the safer way and make the image file then burn from the image file. and can i do the same thing with nero ( tick and untick a few boxes that i dont understand to make a fully booting copy) because the main program my friend uses is Nero so i won't have to download it.
Thanks again to all who helped
