Sky/Freeview setup help

[philchi]

Have had a new sky box fitted today, with the new boxes there is no rf line inputs, had to buy a io module to take the rf in and out, have a good sky signal through to the rest of the tv's in the house, the signal is put through a booster from the sky box, the booster also feeds an amplified splitter which powers the rest of the tvs in the house, both splitter and booster are both powered, now since i have put the new system in the other tvs do not recieve a freeview signal, worked fine with the old sky box, fed up with it now as I have been fiddling with it for over 3 hours,

splitter lead goes to out on booster
skybox goes to in on booster (other end connected to io module)
rf/ariel goes to in on io module
io module connects to skybox

Head is done in if someone could help I would be most grateful

Thanks

Philip
