If the error says that it can't load the model,
usually it means that it cant find it.

If your model is in a folder called "models" for instance,
in cScript, you need to include that information in one of your .wdl files.
I usually do this in the .wdl that contains my "main" function.
Adding the script...
Code:
PATH "models\\";
...will let the engine know to look in that folder for game assets.
If you are using liteC you will have to set these paths in a .wdl
file, and if I'm not mistaken, the name of that .wdl needs to be
the same as the .c file that contains the "main" function.
If I am mistaken, I'm sure that someone here will set me straight

Anyway, you need to make sure that at the very least any models that
you are using are at the same level as the script with the "main" function.
This error usually means "I can't find the model" not "There's something
wrong with your model and I refuse to load it"
