If you are unable to play the video, then you may be using a very old browser or a non-standard web browser with extra security. Try the page in a different web browser, such as Chrome, Internet Explorer 10 or above, Firefox, Opera or Navigator. The videos use the html 5 layout and will play without Adobe Flash or other plugins.
1. Check the volume. There are two main places to check: in Player window's control bar in the video window itself, and on the lower right side of your computer desktop, in the taskbar tray, on the right side.
2. If you are using speakers, make sure your speakers are turned on and the volume is turned up on the speakers. Also make sure that they are plugged in to power (they will have either a USB connection or a power cord) and the proper ports on you computer. Your speakers will have a small jack, often green, that plugs into a hole in the back of your computer, usually marked with a green circle. If there are holes marked with red or black circles, those will be the wrong places.
3. If none of these things work, you may need to get someone to check for a problem with your soundcard or settings.
Enlarging the type in the PDF window:To open a case file in a new full sized window, click on the file name in the case file box. The case file will pop up in a separate browser window as a PDF document. You can enlarge the case file in several ways: by clicking on the + sign in the Acrobat toolbar; typing in a higher percentage in the percentage box on the toolbar; or by dragging the lower right corner of the window to the desired size. On a tablet or smart phone, you should be able to expand the view with the usual touch gestures
Problem: You click the link, but the PDF doesn't appearWhen you click a resource link to a PDF, the PDF is downloaded to your computer and opens in a new window. Some of the PDF files are large and take a few minutes to download. If you don't see the PDF after clicking the link, give the file more time to download, and look for a new browser window that may be hidden behind another window.
You can check this by looking at the taskbar. The taskbar is usually at the bottom of your screen, has the clock and other icons, and shows what programs you have open. Look for your web browser program on the taskbar, either showing more than once, or having a number beside the name. This lets you know how many windows are open in the browser. You can find and click the browser window that has the PDF file on the taskbar, so that it will pop up in front of the other windows.
