There are a number of ways of getting the plug-in you need:
Visit the Macromedia Shockwave site and download the Flash plug-in for free. Their site offers plenty of advice and answers to common queries about plug-ins. Once on the page follow the steps (make sure you don't miss step one - click the auto install button).

Alternatively another option would be to install the latest version of your Internet browser for free, which have the plug-ins built in.
