Bump mapping problem !

Hi
After enabling vertex and pixel shader in material/technique/pass
for my sphere and selecting "Examples/BumpMapVPSpecular" from combo, and also selecting two images for texture unit 0,1 :
wall.tga
wallNormalMap.tga


i have no preview from my mesh!
if i disable vertex and pixel shader section, then i have preview in oFusion viewport but without bumping.
oFusion don't allow me to edit the vertex and pixel shader code, i don't know why! but "edit" button don't work.
Anyone can help me?, i only want enable bumping on my simple sphere.
i have 2 images:
wall.tga
wallNormalMap.tga

Maybe CE version don't support bumping?

Do your video hardware supports the needed shaders?

Search this forum, there are several good bump mapping shaders for download in some threads

The CE version support shaders, any bump mapping shader should be supported
