First of all, I am new with Impulse and my first game is Demigod from Impulse. I downloaded the game and archived it. It created "Demigod1.00.091_05.23.2009.impulse" file. My question is; this file is enough to restore the archive? Also I am using Acronis TrueImage to backup and restore my OS (I don't make new install). I heard Stardock is using activation for games and applications (and there is a limit for that, I don't want to get in the trouble with activation limit is reached) and I am restoring my OS nearly a month, if I backup sig.bin bile in Stardock\Demigod folder and copy file to same location after the Acronis restore process of OS I don't need to activate the game right? Because OS is the same, only restored. I hope you can answer these questions, thank you.
