as most of us know on the downloads page there is a soundtrack you can add to the game consisting of 17 songs, does anyone know where did it come from?
Initially you will be granted 3 unlocks. In addition, you get an additional unlock available every friday, provided you do not already have 2 unlocks available. So unless you are having severe problems with your computer, you should be fine and always able to unlock LFS again after a reinstallation of Windows for example, or when you buy new computer parts or a whole new computer.
