How do I safely uninstall mods added to borderlands 2?

Question

A while ago, I added this mod to Borderlands 2. At that time, my Borderlands did not include any DLCs or other mods of any kind. However, a week later, I bought the following DLCs: "Krieg The Psycho", "Borderlands 2 ultimate upgrade pack" and "Tiny Tina's assault on Dragon keep". On that day, when I opened the game, an error pop-up came up, saying that the Game was removed.

Another thing that I would like to inform you is that I have tried uninstalling the game but it only says that the game has already been removed or uninstalled. However, when I attempt to install the game from Steam it tells me that I already have the game installed and the game is still there in my Steam library.

I am guessing that this is probably due to the fact that the mod I installed and the DLCs are conflicting add-ons. I would like to know if there is a way to fix the issue.

In case this might mean something, I use Windows 8.

If you are playing on steam, I advise in any case you first save your characters. Just follow this path : UserName/Documents/Games (or My Games)/Borderlands 2/WillowData/xxxxxxxxxx (numbers)/ Here you can find all the files related to all your characters (the xxx.sav and xx.bak.sav). Copy them and the file named "profile" somewhere else (usb drive, on the desk, anywhere). If you do so no matter how you screw up while remooving the mod, your progression and characters are safe. For remooving the custom mod, I'd go in steam library, right click on borderlands 2 > property > Local files > Verify integrity of game cache. Let it run and steam should patch your game for you.
