Stupid problem with texture coords;

Hi!
Its agin me:P
I rewrite my engine to opengl 3.3.
I try to load models ( im using assimp )
But i have strange problem with texcoords i get this :

Its looks like theres no texcoords? wtf? xd

It's should look like this :

( Every model look the same ( texcoords))

my Vertex Shader:

#version 150
uniform mat4 Matrix;
in vec4 Position;
in vec2 in_TexCoord;
out vec2 out_TexCoord;
void main()
{
out_TexCoord = in_TexCoord;
gl_Position = Matrix * Position;
}

my Fragment Shader:

#version 150
uniform sampler2D tex;
out vec4 out_Color;
in vec2 out_TexCoord;
void main()
{
out_Color = texture(tex, out_TexCoord);
}


I think loading model code is good because its working before on opengl 2.x ;P

Sorry for my stupid question
Thanks for help!
