Backup Problems

delete norton photo.jpg

 

I'm trying to activate my Secure Online Storage. When I get told to sign into my Norton Account I must enter a password for an email address that is not mine. When I try change to my email address I get the error message in the photo. How do I fix this? I need to backup my files urgently.
