moving his entire ~/Library/Application Support folder aside, i.e. to his desktop, to see what happens. Either logging out/in or restarting afterwards is necessary.
I tried it, but the only thing that does is copy the Application Support folder to the desktop. I don't know why that would help. It's impossible to delete the original Application Support folder, if that's what you were thinking.
As for the other post, I assume those are Terminal commands. I haven't worked with Terminal enough to decipher that post.
