Still having trouble

[Franga]

I downloaded CDRwin but when I go to get into it, it says "Unable to initialize the ASPI manager. Aspi support information was not found." and then when I click on the extract Disc icon it says "No CDROM reading device was found on the SCSI or IDE bus!" what does all this mean?? If I was to use Nero do I patch games in the same was as if I was using CDRwin?

Thanks again guys.
