This course uses the Flash player for the video segments. You will need to download the Flash player if you do not already have it installed. Click troubleshoot video to test whether Flash is installed and which version of Flash player you have. Please note: You will need Flash player 10.0 or greater to view the videos in this course.

Resolving Video Player Problems

If you cannot see the video, you can still continue with the course by simply reading the transcripts. The video problem likely is that either the media player has not been installed or updated, or your computer network is operating behind a “firewall” that is blocking reception of broadband media.

A firewall is software or hardware used to keep unauthorized users from accessing your computer, but it can also block incoming data, such as our videos.

First, make sure that you have a recent version of the player and download a newer version if necessary. If you have the most recent version, check whether there is a firewall enabled on your network:

  • For an office network, you may need to ask your network administrator to allow access to the ports used by the player.
  • For a home network, consult your firewall’s documentation for instructions on how to allow downloading of video.
  • Check with your network administrator. Are you permitted to download video? The file sizes are small, but some restrictions may be applied by your administrator.
