Sagem DBOX lost channels

Hi Everyone

I have a Sagem DBOX which has lost most of the channels again.
A week ago I managed to get it working by entering the new code into Tuxbox settings. It worked great for a few days but the shows a blank screen for any of the non terrestrial channels. (still shows program details).

Does anyone know what I need to do this time to restore the missing channels? Is there a newer code or is there more to it? Do I need to connect it to my PC if so where do I get the required files etc??

I realise that this may have been already answered.. but I have trawled through the forums but I'm unsure which information applies to me. Connected to v1rgin in midlands area.
