Norton Security says it has expired when it hasn't

I have Norton Security Deluxe 5 user edition. Today out of the blue, Norton on my WIN7 laptop says it has expired and I can't run it or update or anything. I went to my desktop WIN7/10 machine which one of the 3 seats and it runs fine there and says I have 155 days left on my subscription.  I went on the desktop to contact Norton and got on the chat section with one of their reps who didn't quite get the question and all he wanted to do was have me go to a link so he could remotely control my computer to fix the problem.  I don't like anyone to remotely control my computer, just tell me what I need to do on My Norton to fix this. Does Norton support actually do the remote take over?

Anyway, the Norton chat rep couldn't understand why clicking on a link on a computer that wasn't having the problem would not fix the other computer that actually did have the problem. 

Did anyone see this problem today 1-10-17.

I may just do a system restore

Any response would be appreciated.

Thanks

Ron
