Attached Link: Texture Problems

Hello, last evening I tried to build a keyboard. (Synth, looks kind of a DX7) I used Max 2.5 There are many single objects, the white keys , the black keys and the housing/frame. After that I tried to apply a texture on the frame. I used Paint 3D and Photoshop and put all the pieces were they belong. When I render the image in Paint 3D all looks perfect. But not in Poser. I tried to import it as 3DS or OBJ but it doesn't help much. I can change the color of the frame but when I'm trying to apply the texture the frame went all back. There is nothing wrong with the bitmap, when I apply the texture to an other objects it works well. If anybody want to check out whats wrong, I could send you all the files. (.max .3ds .obj .jpg .psd) Just send an e-mail to iron-man@gmx.de Maybe someone can finaly put the things togeher
