Texture is tiling.. and I have no idea why.

Every time I've tried to apply a texture, this has happened. I painted in mudbox, exported the paint layers and then attached them to a lambert. Didn't work. Then I imported the Mudbox file into photoshop and made sure it lined up with the UV map export that I did. That didn't work.

Any suggestions? I've been banging my head against my keyboard for hours now.
