You don't say which IRAF version this is, but I suspect the file is corrupted in transfer somehow. If you download from the web, be sure to use 'binary' mode, note that depending on the browser you use this isn't guaranteed so a direct 'ftp' or 'wget' is preferred over the "Save As" menu option from a web browser.

As for the CD, we haven't produced one in years so I can't comment on it's validitiy. If you tell me the IRAF version you're installing I can send you a checksum to validate it.
