Did you burn the CD at high speed? If so the most likely problem is that there is indeed something wrong with the CD, and a low speed burn would likey either work or get a lot further.

If the CD was made properly at low speed then you might need one or more cheat codes. But usually you will see something after pressing enter (at least a penguin for each cpu on your system) if this is the case. See the cheat codes section of the wiki or the cheat codes file that you got with the download for more details.
