Snickerer

So I got into modding a few days ago, and kind of broke my game before I realized it with mods, so I decided to wipe the slate clean, uninstall all my mods, then uninstalled LOOT, then fallout 4. But after reinstalling both fallout 4 and LOOT, I get this message in LOOT :Error: Game-specific settings could not be initialised. Cannot set the current game: the game with folder "Fallout4" is not installed. The game boots up, and the only thing I've done so far is gotten the script extender for it, but I have plans to download more mods. So I really need to figure out what's causing this. Especially if it could cause interference with other mods. Can anyone help?
