I recently acquired the Custom NPCs mod for Minecraft. I was aware you could get said mods through Curse Client or download through the client so they could be accessed in game. However, upon doing this, I had to open it with Curse because it was not appearing in the Curse downloads or My Textures. I went into the game to see whether or not it worked and it didn't work. I then tried opening it with Minecraft and it took me to a log in screen similar to the one for Minecraft but instead didn't log me in whatsoever even though I gave it the right information. I need some assistance here. All is appreciated.
Curse Client and Minecraft Mod issue?
