If you can NOT get the videos to play, the ones that are password protected, it is most likely because you are behind a “firewall” or you have some other software that is blocking content from sites like Vimeo, YouTube etc.

If you are at a school, work, or on a non-private network, there is a high chance they are blocking your access to the content. Please use a different network or, have your IT Administrator whitelist the sites.
