Norton 360 Expired Without Warning

Recently, I opened my computer and it said I have turned off my Firewall and Anti-spyware. I noticed that the date was changed to December 1st 2312 for some reason. I changed it back but my Norton 360 expired for no apparent reason without a warning or whatsoever. I had this problem in the past but my subscription would stay the same. Can someone tell me what is going on??
