WPMU Dev Videos not working from Dashboard

I am having problems with the WPMU Dev Videos plugin working on the Dashboard, it worked before, not sure why it isn’t working now.

I get the following screenshot below…

I have deactivated all plugins except WPMU videos and switched to Twenty Fourteen, didn’t work.

I deleted the plugin and re-installed, clicked Settings and WPMU Dev Vidoes and Saved Changes, I have the Videos checked “yes” for add to contextual help…didn’t work.

It says I am successfully registered and gives me a site ID. I went into the “Support videos API” and my site is still registered correctly.

Please advise.
