I am having trouble watching the video lessons, what can I do?

Please take the following actions:

1. Make sure all of your Adobe software is up to date, especially Adobe Flash Player and Shockwave Player.
2. Make sure all your Java software is up to date.
3. Try different browsers (such as Google Chrome and Firefox).
4. Clear your browser cache and cookies. In IE, disabling the compatibility settings resolves the issue. You may also want to try to set to default settings.
5. Refresh your screen/Reboot the system.
