So yesterday I bought the Mount & Blade Collection which also includes Napoleonic War dlc. The problematic part was that when i was registering my CD key in the forum, both Mount & Blade: Warband and Mount & Blade: With Fire & Sword CD key was succesfully registered. However, when i tried to register Napoleonic War dlc CD key I couldn't find" Napoleonic War" in choose game: selection. Instead, I saw Napoleon Expansion which was right below Mount & Blade: With Fire & Sword so I thought this was the one where I should put my CD key. However, when i input my CD key it stated that it is an invalid key. So I am wondering, did i get invalid key from steam or am i registering the CD key in the wrong section?
