Two year subscription

Hi

I purchased a two year subscription and as of 3 hours ago had 212 days left to go before renewal.

Whilst attempting to backup, and installing updates, I find that Norton was updated, installed and then told me that I now only had 30 days of a trial left. Can someone explain whats happened to my original subscription, as having paid for it want it back.  I thought I was just updating...... 

 

Thanks
