Hi, My nephew watched Mr. Bean movie in avi file last week. He used his usb stick to download it in the pc. When I arrived in the evening, strange thing happened. I couldnt sign in to the administrator account! It seemed that the pc forgot my pw. I tried to delete the avi file from the guest account but windows said cannot be deleted the path cannot be found. Mine is windowsxp and I dont know how will I be able to retrieve my files in admistrator account. Im clueless and helpless..pls help me.
