Norton is not working

Norton says to restart my computer and I did and now I have an X next to my Norton icon and it does not update and it now says my subscription is over when before I restarted my computer it said I have more than 75 days left.  What happened??  I called the 1-800 number and I waited for more than 2 hours now and they asked me to join the forum for help. Can anyone help me? I have rebooted and restarted twice now.
