I am trying to use the Repousse 3D feature in Photoshop CS5 Extended and have been unable to figure how I can get it to be an option using text. Can you explain how I do this, please?

I have also tried rasterizing the text first and that does not work. I have tried placing the image and them loading the selection and I still do not have the option of Repousse.

I believe the issue is with my OpenGL. In the System Info it allows Normal Mode but does not allow Advanced Mode. I spoke with the "Geek Squad" who advised that this is not an issue with my Mac but has something to do with the software.

Can someone please help me fix this?  Thanks.
