I recently bought Mount and Blade: Warband for my PC, but am having a bit of an issue with putting it on Steam (which, to my knowledge, is the only way to play it). I am being asked for a "product code", which is located "on the DVD jewel case, manual cover, disk insert, or inside the case under the disk". The code, according to a Steam support topic I found, must be 13, 18, or 25 characters long. The only code I have found is 24 characters long, and, of course, Steam declares it invalid. I have searched far and wide for a solution and asked every source possible up to this point. Anyone have a solution?
