I hooked up an older shaw box (its silver) to my tv tonight as our tv said we now need a shaw box to continue watching our channels. My in-laws gave it to us as they switched. We live in a basement suite and cable is included. I set up the box and everything works except we only get channels 2-28 the rest say "not authorized" I know they have a full cable package. What could be the reason? Do I have to let them know so they can activate the extra box?
