I am stuck

I have spent the last 12 hours trying to import my character fbx file into unity using a tutorial provided all about lerpz the alien that shows how to import characters and textures and setting it up and scripting everything so that the character works but when ever i do this i get my character walking around in the provided gaming environment totally invisible you can see the movement happening but there is no texture.I guess all i can keep doin is keep tryin.
