UV Problems When Model Imported Into Unity

Hi everyone, this is my first post here and it's one that's really bugging me as I've had nothing but problems with this project I'm working on. I have a relatively simple model in 3DS Max, which I have unwrapped and textured and it looks fine in 3DS Max, but for some reason, when imported into Unity via both .fbx and a raw Max file, the UV's seem to mess up, meaning any texture I place onto the model is oddly distorted, take a look at the images and what I mean should become clear.

I've tried numerous re-imports, changing the 'Swap UV' value, changing from Tile to Clamped etc. Basically I've Googled everything I could think of to no avail, hoping someone here can save me!

Here's some pics of the problem:

Thanks in advance.
