Blade BM7000S Still baffled and channel less...???

Hi guys, I'm still at a loss as to why this bloody BladeBM7000S box is showing all channels apart from fta as scrambled..We moved house last August and had it all reinstalled and for a while, all was good, then after a month or two,, channels were freezing...bloody annoying when you're trying to watch a grand prix, then everything packed up....before our line subscription ran out..!!!
Anyway, as we'd just moved it got left for a couple of months with other stuff to do. Last week I bought a line on a months subscription ...thinking a month would give me ample time to get the b*stard working again. This was my first time at trying to input a line myself, previously I'd paid someone else to do it who now refuses for reasons best known to their selves to come out and help, or even sell us a new box...Obviously dont want our money..
Anyway, I'm now on a second line issued by the same guy I bought the months sub from, and I've double checked I've put it in the Blade correctly. I've bought a brand new quality LAN lead to go into the Virgin media 'Superhub' which it worked ok with before, tried swapping over leads and back again (we've an LG 47 inch smart tv, internet works fine on that...), tried re booting box and router, and everything everything else I can think of. Gone through the beginers guide to Blade above meticulasly, but it still annoyingly keeps coming up with 'disconnected' in the 9991 menu' and all the sly channels are still frozen. I've spent a week at this off an d on and got no where..I've run out of ideas. Dont suppose anyone else has any or could the box be knackered? I don't know how to test it...It logs onto the internet from the menu ok....but I am baffled...and p*ssed off...Had the dish re aligned this week too by a guy who was interested in the card sharing stuff but had'nt done any as yet...Oh, and firmware and channel lists are up to dat too.
