eurovox max 2006 or 2007

hi
this is the first time i am commenting so any help wold be grately appreciated. i have a eurovox 2006 or 2007 box, and yesterday it stopped working first time in like a year and a half. all my channels r gone except bbc1,bbc2,itv,ch4,5,itv2,itv3 and basically them kind of basic channels. on the main channels like sky sports and movies and that it says code updating message. can anyone help me sort out this problem or is the box finished. i am with v i r g i n media in the wolverhampton, west midlands area.
