It is a widespread and common problem that suddenly one or more apps do not show up in your Market anymore. You can't do much about it, except for removing the app and reinstaling it. But as you say, you will lose all progress. To avoid this, you could try to manually download and install/upgrade to the newest version. There are some tutorials on the web, but it comes down to searching for the app's .apk file (so in this case Paradise Island 1.0.21 .apk) and then download it to your phone and run the installation. Hopefully this method will preserve your progress!
