Norton Internet Security says it is no longer working.

I purchased a laptop computer 4/15/11.  It came with 30 day free Norton Internet Security.   4/23/11 said no days of free registration remaining.  I downloaded a 30 day free trial 4/25/11.  Still showing "X" over Norton icon.  Attempted to use support and became very frustrated.  How can I contact someone at Norton who can really help me.  If I can't solve this soon I am going to  uninstall Norton and install McAfee from my other computer which still has available licenses.
