I am trying to download the trial version of After Effects, and it goes through the whole download process fine. But as soon as I try to launch the application, I receive the message "After Effects warning: Could not rename the file '/Users/Rebekah/Library/Preferences/Adobe/After Effects/11.0/Workspaces.35974.1407352380644801.xml' to 'workspaces.xml'.
What is causing this and what should I do? I've already tried uninstalling the trial and reinstalling it.
Thanks!
