I had Norton Mobile Security 2.5 and Anti-theft installed on my phone and working fine. Then I had to do a factory reset because of a buggy app. Now Norton Mobile Security is working fine again but when I try to login from the anit-theft app on the phone with my Norton Account it says the license is registered to a different Norton Account. I only have one Norton account and it shows the purchase of Norton Mobile Security. Logging into the anti-theft web site through Internet Explorer it shows my phone under the device listing. So I deleted it and reinstalled anti-theft again but it still says the license is registered to a different Norton account. Looking at the reviews on the Android market this seems to be a common complaint.
