I replaced NIS 2011 with NIS 2012, retail box (saved money). Before installing, I backed up my identity safe to my desktop, and then ran the Norton removal tool to delete NIS 2011. The install for NIS 2012 went smoothly, but it will not accept the npm file so I can recreate my identity safe. It reports the file is either corrupt or has an unsupported format. Am I just simply screwed here?
