It could well not be that PrPro CS 6 does not have all of those, but that it does not have the version in Pr 5.
Also, after I typed my Reply above, and then saw your response, I realized that your Project is from Pr 5/5.5, and not CS 5/5.5. Otherwise, I would have told you to list All Files, to get to those old Project files, but you covered that with *.*. I have worked with several Projects from Pr 6/6.5, and as those were from a Mac, I had to first add the .PPJ file extension, just for PrPro to see those files.
In my cases, there were very few "glitches," and they all revolved around Effects that had existed in Pr 6/6.5, but not in PrPro (my version), or 3rd party Transitions. In every case, PrPro gave me a dialog screen, with the exact TimeCode, and the name of the "missing" Effect, or Transition. It was easy for me to investigate the missing Effects, and then just add the current versions to the Clips in question, and PrPro told me exactly where to look. Same for the missing Transitions, which I just replaced with Cross-Dissolves.
Sorry that I missed that the Projects were Pr, and not PrPro, but you figured that out.
Also, as Greg alludes, there are some Effects that ARE available (though they might well differ from ones, of the same names, back in Pr) on the PC, but are missing on the Mac. Think that there are a few Transitions, that are missing too?
Good luck,
Hunt
