They played fine for me.
Try Clear Browser Cache

Also the Ebook gives me a error and says unavailable.

Still won't Play.  I cleared everything and even tried it on Edge and Chrome

Does it play if you download the videos (see Resource section)?

Hi Chris

I have no problem on my computer, can you check if you can run lessons from Biggened 1?

Kevin it does not I get Site not found

I also get the same thing if I try to look at the ebook.

Try signing out of your account and signing back in again.
You could also try restarting your computer.

Ok I figured out was what going on... It was a firewall issue.  The video's and everything work on my phone but not my PC....   Thanks for all your help!

Yep. This is in my Videos Not Playing FAQ page.
