Hi Sarah, The first Terminal command to clear ACLs typically did give error messages. In all cases it was OK to ignore them. It attempts to recursively remove previous access control lists.
The second Terminal command with the: chmod +a "everyone deny delete" ~/ ~/Desktop ~/Documents ~/Downloads ~/Library ~/Movies ~/Music ~/Pictures ~/Public (everything in one line) is supposed to do the heavy lifting correction. This basically sets up an access control list that denies delete access to everyone but you for files in your user account. Did you manage to run the second command in your Terminal session? There were a few posters who thought that just running the second command by itself would work to fix things. HTH.
