Photoshop :: Program Error When Try To Use 3D Repousse In CS5 Extended?

Unable to use 3D repousse Photoshop CS5 Extended  (my system info is described below)I tried almost everything that is available in Adobe library, also re-installed programs as requested by Adobe support (suspected to get rid of me), it did not solve the problem.
 
I used to have 3D capabilities, and also crop tool worked well before (now it changes all layers when using crop even in background).  My PC is same,  nor I downloaded plugins or changed video cards (these things are too advanced for me!), also restored preferences many times.
 
My system makes automatic updates, reviewed graphics and adobe as recommended. OpenGL settings is odd …only can access basic, other modes are not highlighted (normal or advanced).

ERRORS (for 3D Text)    
1-“Your 3D scene now exceeds the limits of lights and/or textures for the video card’s hardware-accelerated 3D rendering. As long as the limits are exceeded, 3D rendering will be done in software only, and some features (e.g Repousse)will be disabled.”
2- “Your video card does not meet the requirements for hardware-accelerated 3D rendering. All 3D will be rendered with software only “
3-“ Could no complete the text layer command because of a program error”

ERROR (for object)
Open GL/GPU HARDWARE ACCELERATION IS CURRENTLY  DISABLED. 3D WILL NOW BE RENDERED WITH SOFTWARE ONLY.  TO ENABLE OPEN/GL  ACCELERATION, GO TO PREFERENCES > PERFORMANCE TAB AND CHECK THE “ENABLE OPENGL GRAWING” CHECK BOX.

Is it possible that I have a GPU Sniffer? all these terms I have learned recently =)   but I have a healthy & capable graphic card and accepted by adobe standards.
