[SOLVED] My TMNT Van turns Purple! Why?

I found a model of the Teenage Mutant Ninja Turtle's Party Wagon and I converted it and then remapped the UVs. It looks okay in S4Studio, but then whenever I put it in game, it turns weird colors, and the certain colors are always in the same places.  (Example: That lime green at the base of the Antenna and back of roof.)  No matter what base model I use and replace with the Van mesh, it will look the same in-game. Is it something with my blender mesh? The package file settings?  I'm still new to this so I don't quite understand thing like Bump Normals and things like that, but I'm learning.

I know it's higher poly, but if I take it down anymore, it warps terribly.
Here is the package and blender file.

I appreciate any time and help you could spare.
