Updating to Shivering Isles-Oblivion

[refraction]

if you update to 1.2 before putting shivering isles on, you actually get a newer version of oblivion out of it. if you notice SI has an earlier build number, but if you put the patch on first, SI wont update it n youll have the newer release, at which point the 1.2 NOCD's will work, but its likely the SI ones won't.
