I have signal but magic eye not working!!?? Any help please?

Hi, I have a magic eye which has worked for a few years now. The problem is I have now up my sky+ box in the bedroom instead of the lounge and wired the connections through the wall our new extension via a distribution unit in the loft. I have signal and the light is on on the magic eye-TV link but I cannot change the channel or use the remote in any way. Can anyone help me please? Many thanks
