I have a Syncmaster LT27A950 with T-GASMDEUC-1007.0 firmware and I would like to install the SamyGO widget. All steps ok until I get to point 3. "Press User Application Synchronization". This continually fails with "network or server interference occurred"

The Monitor is connected to the Internet (wired) via 2 switches and a router (all Netgear) and I gets is IP, GW and DNS via DHCP. There is no proxy and I don't think anything is blocked by my Dutch ISP (Ziggo)
If I ping the IP in the instructions from my PC connected that is connected to the same switch I get this: -
$ ping 149.154.159.134

I have changed the SMART hub locale between NL (my location) and UK (country of origin) and all widgets install and update as expected. I have also tried a complete reset of the SMARTHUB, again this had no effect.
I managed to download the Netplayer widget from 91.121.84.162 using this method with no errors at all.
Has anybody any idea how to work around this? My goal is to remove PVR scrambling. Can I achieve this in any other way?
