Sorry to hear you're having difficulties. Are you sure you got v. 1? I don't know how that's possible.
In v. 2 (which is what I have), there is a choice on the left-hand menu that clearly says "Sync". Click that an it syncs with your on-line Premium account. Couldn't be much more simple.
Did you try the email support contact? I've never had to, but it would be worth a try.
Oh, and please don't give up, FitDay PC is awesome and well worth the price of admission (though I wish you'd got the $19.95 price). I use it pretty much exclusively and love it.
