Hello,
I don't know a ton about this stuff, so please bare with me. My problem is this; I've been playing Oblivion on my laptop with a ton of mods for a while now. However, alot of them require Shivering Isles. So, I tried to find an online download for SI. However, I couldn't find a place to simply download SI. I tried the gamesas store, or whatever, and every time the page was down. I don't trust torrentz and things of that nature, so I decided to simply buy the Oblivion Deluxe Edition from Direct2Drive. My intent was to download that, since it came with all the DLC AND Shivering Isles, and only install SI and the DLC to my "already installed" Oblivion. However, now i'm at a loss, because it installs the full game into a folder right below "Oblivion" called "Oblivion Deluxe".. so now I have two oblivions... The problem is, I do not feel like transferring all of my mods over to the new version... nor would I know how. I also do not know how to transfer my saved games and do not want to lose them. Soooooo...

Can anyone please tell me how to install ONLY the Shivering Isles expansion to my pre-existing version of Oblivion? Thanks in advance.
