Hey, so I attempted to copy and paste the objects and even layers into cs4 from cs5 and it would not let me. I did however, find a solution.

You need to export the cs5 project as a Premiere Pro Project. You must then import this new file into After Effects cs4. It won’t know were the files are until you reload them(also, it didn’t treat my image sequences as sequences, so you will have to manually re-find every image sequence file). Also, it didn’t import keyframes, but it did import some effects.
