I had an original copy of oblivion. Then I found out about the GOTY edition and how it comes with Shivering isles. Since I didnt want to pay 2400 MS points (30 dollars) for Shivering Isles, I bought a copy from my friend for $15. However, disc 1 is hopelessly scratched. (I did know this before I bought) And I can't play Shivering isles. When I put in the white version of the disc (not the GOTY one), it says that the extra content failed to load. I guess this is to prevent free distribution.
Is there any way to play the installed version of Shivering Isles without using the GOTY edition disc?
Thanks
