Video will not play for me.

Note: If you are having video playback issues with either The SLII Challenge or Learn the SLII Model Online, please see this help topic, instead.

If a video fails to play or is choppy, it could be one of the following issues:

1. Your internet connection may not be reliable enough to effectively stream the video.  Ensure you are using a high speed internet connection and use a wired connection (not wireless), if possible.

2. You may not have the latest version of Flash installed - Go to to ensure your Flash player is up-to-date*.

*Note: For advanced users, you can also use an internet browser capable of supporting HTML5 video if Flash is not an option.
