I've never bought a game via download so I am curious as to...
1.  will I be allowed to put it on both my desktop and my labtop (and just pay once)?
2.  will I be able to re-download it a few years down the road when I buy a new pc (or have to get a new hard drive)?

Sorry if this has already been addressed somewhere - didn't see it on forums or in a faq.  Seem lk the manual for the gold edition mentioned that Stardock was cool with having 2 computers in the household running the game on the same license.
