I purchased the game not very long after it was released, before any patches had come out, I believe. Unfortunately, since then I was forced to remove the game from my hard drive due to a lack of space: I was thinking that it would be only temporary, and then when I had more space I would re-download it. However, it turns out that the download link I received in the email sent to me no longer functions. So, I can no longer download the game from that link. I still have the serial key and all the other information in the emails, which I hope functions. Any help?
