Hi Bruce, and welcome! First off, where in the world are you? You never know, there may be someone living quite near to you that could do this for you. Failing that, I'm sure plenty of people will be willing to help. I'd do it myself but I don't have a copy of Final Writer here... If someone does though, it's a simple task to convert those files into something you can read with a PC/Mac.
If you want, and can't find anyone here to help, I can have a look at the disk and email you the files from it, so at least they'd be preserved until you come across someone who does have Final Writer...
