but i dont have an oblivion.exe file.or if there is where is it at i didn't see one. OBSE loaded fine before until i accidentaly uninstalled it and had to download it again.

It should look like this, just extract all of the files from OBSE into the Oblivion folder. http://i438.photobucket.com/albums/qq102/Starforce9/OBSE.jpg
