Saved mod over folder.

[CookieMunn]

So, I was installing mods for the first time, and I came over some pretty cool retextures for the adept robes called assassins creed retexture or something, I downloaded it and began playing. After some months I got sick of the retexture and wanted the old look back. I tried deleting every folder of skyrim I had, reinstalled the game about 3 times, but nothing seems to work.. I think I saved over the old folder or something (And I don't have any backup file) so is there any way to like.. Delete the whole game and its content / saved folders, without having to pay for another CD of skyrim? Please help, asap :)
