Need help with Model import

[NNDanny]

Well, I explain the problem. I imported an 3D model over Link, using Link's bones, and all that stuff. It even worked... Before I wanted to improve the textures. You see, it's hair was not using the correct texture, so I changed ONLY it's hair texture, using another type of one of that options texture import gives you, and here, it made boom.

Now, no matter how I import it, the compression I use, the option I use for the textures, it doesn't matter anything, Brawl won't make it work. Please, if someone can tell me what I did wrong, I'll be grateful.

PD: If anyone needs the FitLink00.pcs, I can lend it, but I don't like to upload things that aren't finished.

Here, a little list to make it simple to understand the issues:

-The character is a Link import, using Link bones.
-The character used to work.
-The character worked when I compressed TextureData[0] with LZ777, but without any texture.
-The test imports filesize were between 650 and 900.
-Normal Link textures work.
-The problem doesn't ocurr only on Link's 00 texture.
-The model shows on Brawlbox without any problem.
-I tried to use another FitLink0X.pcs, reimporting the model and textures, no luck.
-As long as I remember, the textures I were using had 3 I4 and a CMPR, with the last being CI4 back when it worked. I just changed the CI4 to CI8.

I hope someone can help me. Thank you for reading and sorry if this is not in the correct place.

EDIT: I fixed the problem, but if someone can tell me why this does happen, I'll be grateful.
