Bought a DLC for FGII on Steam - Cannot access it
I just bought FGII and "PFRPG Basic Paths: Fangs from the Past" from Steam. After running FGII, I cannot find the DLC. In Steam under FGII's DLC, I get the following message: "You currently have no downloadable content for this product.". I own a Mac and am new to FGII. I got by email a receipt from both Paypal & Steam Store that everything was purchased. In Steam, it says that the DLC is in the Library. Can anyone please tell me what I am doing wrong? Thank you very much for all the help in advance.
