 * When I use auto-install, I get the message, “The plugin does not have a valid
   header”, but the plugin seems to be working fine so far.

 * I’m getting this error on a fresh install too. The plugin has worked previously,
   it must have something to do with the latest WordPress upgrade?

 * Plugin doesn’t work on my fresh WP-install. I get the “header” error. If I install
   manually I get no error when activating, but the plugin still doesn’t work. It
   works on all my old installs. I’m guessing something with the plugin activation
   process not compatible with latest WordPress?

 * I had the same problem. I then changed the theme from a custom theme back to 
   the ‘twenty fourteen’ theme and was then able to activate the plugin. Might be
   worth giving that a try if you have not already done so.

 * Can you try the latest version? Only the version changed, however, there was 
   a report of the download from a few weeks ago containing the trunk folder so 
   something may have been corrupted.
