It appears Win10 Creators Update killed the gadget for some reason. I have the gadget on my laptop which is not the Npvr machine using 8gadgetpack. I'm getting "Connecting..." in the gadget but it never updates the gadget with the pending recordings. Interestingly if you click the "Connecting..." the window pops out and it's populated with the pending recordings as normal so it's getting some data.
I can ping the Npvr box and http://your-server-or-ip:8866/public...s/infoxml.aspx returns. I've disabled the firewall & virus scanner both with no change as well completely uninstalled and reinstalled the gadget.
