Texture not applied on model...

Hi, I have an interesting problem, I hope somebody met whit this before, and solved it successfuly :)

There is a 3d model in .3ds format, exported from allplan architectural software. There is a 225x225 brick texture in jpg format.

When I put this texture into the slot on the models material, only the color will be visible, but not the texture. I attached a image about this problem.

My first tought was, that the model is wrong (for example mirrored normals). So I checked it in blender: I put a texture on it, then rendered, but in blender the texture was visible. I'm not really into in modelling, so I can't investigate further without help.
