EURO VOX max .. Urgent help needed please :-) !!?

Hi there this is going to seem like a bike story but i have major problems...

My girlfriends gran passed away a few months ago and we was given her eurovox max box, which was working fine for her in scotland..
I got the box back to my house in Cambridge England and plugged it all in..
The box had 44 channels but was saying no signal, i done a full scan which took me ages and it found over 700 channels but i was still getting no signal..
So i decided to format the box from the menu options and i have now lost everything...
I can now not even do a scan because i have no channels and it does nothing when i click on the scan option..

Can someone please please help me out as i dont want to let the box go to waste as it means alot to my girlfriend as it was her grans box and iv meesed it up :-(

If you can help please reply to this question.. Thank you so much.
