How do I upload models?

How the hell can I do it? It never works. Just shows a damn yellow checkered box. And don't tell me to read the damn tutorial, because I did, and it didn't help me at all.

Hum hum hum it sounds your having trouble getting models to work than uploading them?

I've been having the same problem. I've checked my file paths, and I know they are all correct, and it still doesn't show them. I've tried using the Units and Texture paths that alot of other models use, and that doesn't work either. I really need some help.

What model is it?
