The icon in my task bar has a red "x" on it.  When i open the program, it says my definitions are not up to date.  I run LiveUpdate, after it's finished, it still says they are not up to date.  Sometimes it tells me i dont have any to update but yet I still get the "my definitions are not up to date". I've tried going thru the chat process, my computer wont allow the chat site to open, it says its an untrusted website because of an invalid certificate.
