3D in CS5 Extended

[RFPhotography]

I'm trying to play with 3D in CS5 Extended and not having any success. 

When I select the text layer that I want to work with, I then go to 3D>Repousse>Text Layer.  I do have Window>3D open.  Once I choose my 3D option, nothing works.  Anything I click on I get the 'ding' sound.  All menu items are greyed out.  None of the 3D tools in the 3D panel work.  The only way I can get back to normal functioning is to quit the program using CTRL+ALT+DEL.  When I watch this video, http://tv.adobe.com/watch/learn-photoshop-cs5/russell-browns-favorite-feature-in-photoshop-cs5-extended/ and see what happens when Brown chooses Repousse I don't get the Repousse screen pop up when I try to go into that option. 

And yes, I am certain I've got Extended. 

Thanks.

Are you using 64 bit or 32 bit? A guess by me that might make a difference?

Good question.  Sorry I missed providing that originally.  I'm on a 64 bit Win7 system.

Have you tried using it in 32 bit?

[RFPhotography]

Same problem.

One possibility. Do you have the latest version of Quicktime installed? It's needed to run videos.

Don't think that's the issue.  It's not a problem viewing the video.  It's a problem in PS that the 3D tools aren't working.

I had a "similar" problem when trying to import a video into CS5 64 bit extended to edit it. I am using Windows 64 bit. The video wouldn't load because it stated that quick time had to be on the computer which I had and it was the latest version. Turned out that I had quick time blocked by my firewall. Possibly similar? I think quick time might be the common denominator? Try

QT isn't blocked.  I don't have the latest version but that shouldn't matter.  Thanks for the link to the Adobe forum.  That is one place that I probably wouldn't go for help.  In my experience, it's the worst place to try to get help.
