I have received a lot of emails from people saying that Dolphin Olympics 2 is no longer working for them. If you are in the same boat, here are a few things to try:
Delete your temporary Internet files. Uninstall and reinstall the Flash Player. Try playing in a different browser, such as Firefox or Opera. Also, it has been brought to my attention that the game does not work in Internet Explorer 7 in Windows Vista. If you are using Windows Vista, try playing the game in Firefox.
