How do I redownload Sins of a solar empire? I bought the retail version, and uninstalled it in impulse (mods where causing crashes). When I tried to reinstall with the disk it gave me errors, So I figured I'd just re-install SOASE with Impulse, but I can't find it. Any searches show my the Trinity, Diplomacy, and Entrenchment. I just want to re-install my game, how to I do so?
