After Effects Conversion HELP!!

I Just bought a new After Effects file that I need to edit but when I open it using After Effects CS5.5 (10.5.0) I get the following error message:
“The file you are attempting to open was created with After Effects version 11.0 (windows 64) and cannot be opened with this version.”

Is anyone able to convert the file so that I am able to open it?


You can ask template author for help.

I have, no response yet and I’m on a fairly tight schedule.

I just need someone with CS6 to take the project, go to file, save as, and go down to save file as CS5.5.
