Unable to create and save new file in Point

After upgrading Point to 6.0 we had an issue with users not being able to create a new file and save. It would give an error of: the file is read-only mode or has been opened by someone else: which we knew was not the case. We logged off of point and then logged back in as the administrator and clicked on File: Rebuild list: After the list was rebuilt we then logged back in as the user and we able to create and save the new file.
