I got the Oblivion GOTY Edition back in 2009, and when I loaded up the 2nd disc to install the 2 Expansion Packs, it worked fine. For the next 3 years I didn't have any problems with any of the content. Earlier this year, I had to delete content off of my Hard Drive in order to install Skyrim to the Hard Drive because my 360 carved a nice little laser scratch into my disk, my friend let me borrow his to install. Anyway, I had to delete Shivering Isles and Knights of the Nine in order to install it. Now, I just got a new hard drive with alot more space, so I decided to redownload everything I had ever deleted off of my Xbox. When I went to go and install the Shivering Isles and Knights of the Nine packs again from the 2nd disc, it told me that one or more items could not be installed. When I checked my systems memory, I noticed that Knights of the Nine had been installed, but Shivering Isles had not. When I went and tried to install Shivering Isles by itself, it still didn't work, with the error message coming up again. I've tried everything, from trying to install it on my old hard drive to transfer over, to clearing my entire system cache. None of this worked and I have been unable to find any help anywhere. This is the last place I intend to look. Hopefully someone here can help me solve this problem. I really don't feel like going out and buying Shivering Isles again.
