Yes, let's get the file out of the lab. If you're comfortable, post it here. If not send it to me privately. You mentioned textures. Have you already created a uv map? If so to you have a version saved that is identical but not seamed & unwrapped? That way if there's a problem with the map we can go back & try a different set of seams.OK, work's on hold until you find anything new... but as Blender itself is very capricious, maybe we should ratha find a renderer (maybe Plotinus?) and move on, if anythign gives us trouble then I can fix it.
If you want to, I can send you a more or less 'clean' version of the file (failed attempts, unused textures, etc. remvoed) anytime you wish.
