Player not refreshing content

The screenshot of status window that you’ve added is slightly odd, especially the download window, 00:00-00:00 is the default download window which should mean that it is always open.

Perhaps just Edit&Save the display profile assigned to the device would suffice, but what you did also should work.

Is that fresh 1.8.3 or was updated from earlier version?

What Windows version do you have on that PC?
is it up to date with all Windows updates, drivers etc?

Perhaps also double check browser emulation in registry, although that should be correct now - Enabling HTML5 in the Windows .net Player
