Need help with custom model

[Shadowfied]

My friend made a mug in Maya for a project, and I asked him if I could use it as an object in Amnesia, and he said sure. So he exported it as a .FBX file (cause Maya 2012 isn't supported by Open Collada yet) and sent it to me, and I converted it to a .DAE file using Autodesks FBX converter. When I opened it in the model viewer, it was just grey, so he sent me the textures, I saved them as .dds files instead of .jpg, then edited the automatically created .mat file (created by ModelView) in the MaterialEditor and ticked the "Diffuse" box and selected the texture. There are multiple textures though, and I'm just very confused...
(And by the way, I'm pretty sure the issue is not that it is made in Maya 2012)

Here's what it looks like (and is supposed to look like) in Maya 2012 (Click the link)

And here's what it looks like in ModelView:

These are the texture files used:

It seems the only one getting used is the "mug_texture_test4_flat.jpg" texture. I've tried making .mat files for each of the textures by making a new material file in MaterialEditor, selecting type soliddifuse and applying the correct texture etc but it ends up the same way.

The problem is that the metal bars around the wood are invisible.

I personally don't know pretty much anything about modelling, textures etc. And my friend doesn't know anything about how to get them working with Amnesia.

I'm sorry if this is confusing, I myself am very confused and I'm in a rush, I'm going to my grandfathers funeral any minute.

If anyone understand our problem and can help us we would be very grateful.

Thanks in advance.
