Advice on BM 8000

So, Im having issues setting up a BladeMedia 8000

I THINK Ive got it set up with the latest firmware, but, another forum I was using isnt letting me download what they claim is the newest, so has anyone got links to this?

If it is indeed the most uptodate, Im having issues accessing the menu to enter an N-line.

Im also not entirely certain what satellite settings it should be set to for when this has been input

Any idiort proof links would help, I find the Techkings one a bit hard to understand and as far as Im aware its different than the BM 7000 (which, if I cant get this to work by next week Im replacing it with, Im not entirely certain what the difference is in the first place)
