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.
