After Effects Installation

[Natalie219682393oxb]

I purchased After Effects on my MacBook and it just finished installing. I tried to open it but it an error popped up saying, "After Effects can't continue: Error while accessing the preference files. Please verify the file permissions and try again." How do I fix this?
