I downloaded your ZIP file thinking it was the model and its files, but it was only a JPG screenshot.
Just so you know, you can upload jpg and png images to the forum without zipping them.
From the image it looks as if the model is not finding the textures or something.
Sometimes the APPEAR1.FPI can mess it up, so try using APPEAR2.FPI for the models appear script.
There also may be a scaling problem if you did not use a stock model to scale yours.
If the model is tiny tiny, then you might not be able to see it.
You made the model a character (ISCHARCTER=1), so it might be better to include some of the other animated states like 2 for walk and 5 for run , etc.
Again, the Official Community Guide to FPSC has an explanation of which animations are set up for which character actions.
It could be something else of course, but these are a few things that can cause problems.
I leave my animmax=100 instead of making it smaller.
If it still doesn't work, then I can take a look at it for you if you post the model and its files here in a ZIP or email them to me.
Let me know if you do not want to post it here (make it public) and I can send you an email if ou give me your email address.
EDIT
I just noticed you use spaces in your file names.
I'm not sure if it would make a difference or not, but I avoid using spaces in file names...
my model.x
would be ...
my_model.x
I replace the spaces with underscores.
The same for the name of the texture file too.
