Weapons Texture Problems

My problem is that then I have imported a weapon pack and installed it on the right place.
G Mod recognises the weapon pack and all the weapons is showing under the weapon menu in the game, but when I chose a weapon I keep getting two texture cubes, one in the upper right corner and one in the left.

Any one have an idea how I can fix this?

Here is a screenshot of the problem

The only thing I can think of is that they are ERROR models, too close for you to read. Try looking at yourself in third person, and see if that’s what they are.

how do I look at myself at 3D person?
