Missing Quicktime Pro

I've used Quicktime Pro for 10-15 years now. I'm running FCP Studio (7) and Logic Audio (9). I noticed today when I went to adjust a frame ratio on a Quicktime movie (ProRes) ... that I no longer have Quicktime Pro on either my tower or my laptop. All I have is the Quicktime Player. For the last few years I've been using both, depending on the job requirement. They were sitting there side by side.

I've done a couple of system upgrades in the last six months ... Leopard to Snow Leopard ...

I never trashed my Quicktime 'Pro'.

Would the system upgrades have trashed my Quicktime Pro automatically? That would almost be a form of theft no? Since I had paid for the 'Pro'. I've actually purchased the Pro at least 2 or 3 times over the years.

What might have happened to my Quicktime Pro?

All ears,

Ben
