Shirley has a point; there may be a file/folder that has had it's permissions changed so that the admin. group is barred from access.
it's kind of a moot point for an admin. as he (or she) still has the right to grant access to it.
you probably could right-click the root Demigod folder and tell it to force some nice rules on all subfiles and folders; as long as the new permissions will allow you and the program access then overwriting the existing permissions shouldn't do any harm.
