This page uses Adobe’s Flash plugin.
Flash is automatically blocked if the plugin falls out of date.
To be able to use our online tool “Splash”, you’ll need to download the latest Flash plugin from Adobe, and restart your browser. You can download it here: https://get.adobe.com/flashplayer
If, after doing this, Splash still isn’t running, ensure that the Flash plugin is allowed to run by going to Preferences->Security->Internet Plugins and turn the Flash Plugin on.
