We tried to change permissions on a document that was read only for all but the document creator. When she went into options and Get Info and went to make the change to read/write, it did not allow her to save the change to read/write and in face, subsequently changed "everyone" to NO ACCESS. Now no one has access to the document including the owner. We tried to copy and move it to the desktop but it says we don't have permission. We tried to change it to a new owner, but it says the names are invalid (and they are all valid names on our network).
We are at a loss.... help?
