Doesnt do anything???

Im puzzled by the glowing reviews because the contact sync looks so straightforward, no options or settings to diddle with, i dont see how i could have messed it up but nothing happens. Using my pc, i found vague reference to a monthly fee subscription but no payment options presented (and i thought this a freebie)
