Update message in HBO Go

HBOGo no longer lets me watch videos, says I need to update my Flash, but I'm running the embedded version in Chrome.  It is NOT up to date, it's still at 18.0.0.209, but I cannot get it to update.  I have restarted chrome, disabled and re-enabled the Flash plugin, checked my chrome components for updates, etc.  There is no update there.  I'm running Mac OSX 10.11.13
