In any case, try dumping all the contents of the CD into an empty temporary folder on your hard drive. Then using Windows explorer, look in this folder and note the file's extension format and the individual file sizes. You can safely disregard all those files that are 1kb. since those are your "cda" files. Then rename the others to the "zip" file extension and then try to uncompress them using your unpacking software (Winzip or some such animal). Good luck!
