I just wanted to let you know that the certificate used to sign the applet expired earlier today. We have the new certificate and have signed a new version of the applet. We are working to schedule an update to the site early next week (March 26) to include the updated signature on the applet. For now, if your browser asks you if you want to allow the applet to run, please choose to do so. If you have trouble with the applet that you suspect is caused by the expired certificate, you can try clearing your browser's cache and restarting.
