Game crashing on launch,  error on Alternative Textures.

Hi, Floogen.
I'm having an issue. 
My game is not loading and SMAPI is giving me a message error from Alternative Textures. 
I unninstalled and reinstalled my packs one by one, but the error just stops occurring when I unninstall Alternative Textures. 
Do you know what is gappening?

Here's my SMAPI log, I hope it helps.
