It would seem that Red Giant Software quietly slipped out some updates for some of the Trapcode plug-ins that were not working correctly in PPro CS4. I'm a Shine and Starglow user, and while these worked in AE CS4, they were defunct in PPro CS4. They now appear to be functional again. You can get the updates
right here. Note that the version numbers on some of the plugs did not increment, ie. Shine or Starglow. However, the files are date stamped as of today.
I really wish they would hurry up with Colorista update. It's getting annoying having to make so many AE compositions just for color effects. The Looks update helped, but Colorista is more important for me at least.
