Right now I'm trying to install the Shadowcrest Vineyard mod (http://planetelderscrolls.gamespy.com/View.php?view=OblivionMods.Detail&id=5474).
First, I tried installing it manually by cutting and pasting it from my Downloads folder to Oblivion's Data folder, then started up the game. No change.
Then I downloaded the Oblivion Mod Manager and turned the Shadowcrest mod into a .odom file, followed the instructions on the FAQ (to the best of my ability--I don't think my version is the same as the version on the FAQ), and started up the game. There was no change suggesting anything had worked, but when I went to load a saved game, a message popped up, telling me something along the lines of, "This game is based on data no longer available. Some objects may no longer be available. Continue?" I selected yes, loaded the game, and found that nothing had changed. (There's supposed to be a letter in the Skingrad Chapel.)
So...anyone willing to walk me through this? I'd appreciate any help. This is a whole new world for me and I'm totally lost...
