Error while accessing the preference files. Please verify permissions and try again.
Hello,
The message below appears when I try to open my After Effects app.

This is the system I'm running:

I've looked up solutions and gone into Library/Preferences/Adobe/After Effects and select 'get info' on the folder, it appears to have read & write permissions.

The only way it appears different, is on other folders, such as Adobe Illustrator it will say my user name instead of 'system'.
Does anyone have a solution for opening AE?
Thanks
Rob
