My norton 360 is going to expire soon. I purchased a new norton 360 with new keys for additional computers. I want to back up my logins so I can transfer them to my new norton account. I tried backing the logins up via instructions in the back up settings. The problem I'm having is it is backing up as a nmp file & when I try to open it, it says program doesn't support the file? I tried to search for a program on my pc to open it with & had no luck I don't know what to do now? My computer is a vista. Any help would be greatly appreciated.
