3D object export for blender from Photoshop CS4


I’m trying to export a 3D object that I did create in PhotoShop CS4 in order to use it in Blender 2.49.
In such objective, I did a saving from CS4 by export as (WaveFront).obj file.

However when I try to open it in Blender, Blender tells me that this is not a correct file !!??

Note: the object is a 3D sphere with a jpg UV-map

Any experience, idea or solution that could help me solving my issue?

Thanks a lot in advance
