I am trying to install Fallen Enchantress on my second PC via steam. When I get the stardock login screen I get an error saying the key is already in use on another account, even though I only have one stardock account. How do I get this setup on my second pc? I've never had this trouble with ANY other game I've bought via Steam (and I have over 50). If this is not possible, this will be the last Starcock game I buy via Steam.
