Ok i just got the Oblivion Game of the year edition, and it has nights of the nine and shivering isles on it already. The only problem is, i cant find the new places! The map looks exactly the same. Are the new locations somehwhere on the old map or in a different place??
well after i downloaded the shivering isles, i had to wait about a day before i got the quest prompt. but it might be different for you
