I cant recive signal for 'THE BOX' ?

I have 'The Box' at home and due to my sky prem, prem +1 and sky modern having bad reception I decided to delete all channels and try recive them again....Big mistake...now i cant get any of the channels to come on screen they all just say...Scrambled or bad channel. Iv tried auto search and manual input using certain codes (ie. 444000,338000,386750 and with qam 64 and 6875mghz) i also used these codes and used the last potion which is enable and disable(iv tried enabled and disabled) but to no avail...please help me...also i would greatly appreciate a list of all channel codes...thaks guys
