Rename the Adobe folder to something like "AdobeOLD". Then, when you launch After Effects, it should rebuild the folder structure with the appropriate permissions.

I am currently facing this problem. In my case though, the folder "Adobe" inside Preferences does not even exist. Do you have any idea why is that?
Please let me know.
What OS are you using?
