please help...DRX550 and BSKYB 2600c1?

Christmas Eve 2009.
Woke up this morning my BSKYB 2600C1 wouldn't turn on, all i had was the 3 coloured lights on the front. Tried unplugging and turning on again but nothing at all. So i went out and bought a new one, this time an Amstrad drx550, only all i'm getting is No satellite signal is being recieved, again i removed and replaced the sky card, but with no joy. Now its almost Christmas day, ive got the family over, all we can do is play the wii and play charades. Please please help. Thank you.
On the plus side though, at least i got an excuse to not watch the queens speech.
MERRY CHRISTMAS EVERYONE
