Subscription countdown stuck

My subscription countdown for Norton Internet Security 2007 has been stuck on the same day for about two weeks. I have run several full and quick virus scans since then and nothing serious has come up, only tracking cookies. My computer seems to be running fine, though there have been occasional internet crashes. I have looked for this same problem on other sites but have not found it. I might be making something out of nothing, but I am worried that a virus may be affecting Norton. Any help would be appreciated.
