Sly Sports- is it just me?

I have a 5402 Super, and trying a Sly card in it. It seems to clear most of the subscription stuff, but not sports 1, 2, 3 & 4. SS News OK. Tried 2 cards, updated to Phntompatch 1.28 but still get the dreaded 'Scrambled channel' message. Am I missing something?
And does anyone know if the box will keep the card alive after the six weeks?
Thx, TT.
