I bought Oblivion off of Steam this morning, so I don't really know about modding this game. Anyway, I downloaded a bunch of mods and tried installing them manually using the Planet Elder scrolls guide (which is basically copying each mod into the data folder located in the oblivion folder), and that did not work. I'm running Vista, so I disabled UAC. Still nothing. I then moved my entire Steam folder so it's directly on my C drive, as opposed to my program files. Still nothing. My friend said I might be doing the manual install wrong, and recommended that I use the Oblivion File Manager. I reinstalled Oblivion to get rid of the other mod files, and downloaded each one again. I used 7zip to extract them to their own folders on the Desktop, and loaded them with the "Create" button. I selected each folder from from my Desktop and immediately got an error message saying there are .esp files in a sub-directory or something like that, and it asked if I wanted to continue. I asked my friend about it, and she said to ignore that error and press continue, so I did. All of them activated fine, the launched detected them when I checked the data files, and I just launched the game, and STILL NOTHING. Ughh. I have no idea what to do.
