Some more information would have been helpful, like which 3d modeller you are using and into which format you are exporting.
If the model has been already been unwrapped export it into the .x file format. The UV map information will be exported with the mesh. You might want to apply an empty material to your object before exporting and just reapply the texture inside DBPro.
After you have succesfully exported your object, load the object, the textures and apply the shader.
