So I posted a question yesterday, and I still have yet to resolve my issue. More or less, I'm having trouble playing the expansion levels in my physical copy of The Collection. I had installed the game, and beat the campaign and started the first level of the Dark Below and beat it (I had not been prompted to enter any Activation Codes at any time). And then suddenly, I was told that all of the expansion levels (Dark Below, Taken King, etc.) were locked. And of course, as irony would have it, I think I threw out any activation codes that may have come with the game. I don't really know what to do. My girlfriend has the receipt of purchase of the game. And I don't really want to have to buy the expansion packs again. But I also don't get why I'd need the activation codes if I was able to play the first level of the Dark Below at first. Can anyone with the physical copy of The Collection help me? I just wanna play the game.
