I have adobe after effects CS4 and I need to load a CS5 project.Is that possible ?
No, not directly.
If you can get access to After Effects CS5 (or later), you can use the script pt_OpenSesame to convert the project file into a format that you can open in After Effects CS4.
You can either get the trial version of the current version of After Effects to do this, or just ask someone who has After Effects CS5 or later to do this for you.
