I recently purchased a copy of Pillars of Eternity off of Amazon. I love the game by the way and am now trying to buy the expansions. The problem I'm having is the PC version I bought came with CDs but no CD key (I assume this is normal as the packaging looked legit, it was sealed and the game worked). It appears that the expansions are fully on Steam i.e. no disks but my retail version is not recognized by Steam and Steam will not sell me the expansions without it. I've tried contacting Steam to no avail about getting my copy recognized. They say without a CD key there is nothing they can do. How do I get CD keys or Steam to acknowledge the game without having to buy another copy?
