How to know when there is a new version of Norton N360

Dear Forum,

Until just recently I went to do a full back up with Norton N360 - It then proceeded to give me an error "8504, 104" - I then had to uninstall and reinstall the new version.

I never knew that there was an issue or a new version of Norton and am very frustrated with it happening again.

Last time I was informed by a webchat technical assist. I always try my best to try and check that I am operation the current version.

I am a non tech savvy person, so any assistance would be grateful

I am unsure on how to upload pics to the body of this text - hopefully the above may assist
