Merge to HDR Pro (CS5) Not Working
 

I'm having trouble with "Merge to HDR pro" in CS5. I'm going from Bridge. Once it loads into photoshop instead of creating a single HDR image, I've got a multi-layer image.

I've tried everything from 3-8 images at once. Restarted/updated programs/rebooted. I'm at a loss here and haven't found any real answers in any other forum.

Thoughts?
