|What word processing program is installed on the computer you are using to read those disks?|
Microsoft Word has conversion files you may need to install in order to read the disks. If you have MS Works I don't think it can read those disks.
If you have Works, which is likely, try downloading Open Office, which is free and works well. The first link below is for the download of Open Office. The second link may help you in the conversion process.
