Some of my irreplaceable data files give me a file access error when I try to access them as administrator, or with my regular logon ID. These are files and subdirectories that previously had FULL ACCESS granted to the everyone group. When I try to view security information I ether get an insufficient rights error or a blank list with no user or group listed. I get the message that I can not change security, but I can "take ownership" and the owner is listed as unknown or ownership information unavailable. When I do take ownership, it appears I still cannot alter the rights. I do not have a system state backup, an emergency repair disk or any other means of restoring the state before this happened as the install was just completed yesterday and the data entered today.
Am I SOL or is there some way to regain access?
