I'm not sure you can preload things you haven't paid for. Pinkie Snarq 08/25/09, 05:40
how do i preload games that are allready out? ive heard that team fortress does a free weekend....but i cant find how to preload it on steam. so anybody know how the hell i do that?~
Or things that have already been released.
Preloading is intended to alleviate the sudden rush on the servers when a high-profile new game comes out, thereby saving Valve money.
There's no incentive for Valve to allow you to preload just anything anytime without paying for it first. It would cost them money and it wouldn't improve the gaming experience of people who aren't freeloaders like you.
