I'm having a little problem with BitDefender AntiVirus Plus 10 Updates. It was working fine before but today it started to say that I have an Invalid key and it has expired so it can't update. However in the registration section of BitDefender it says my key doesn't expire until 2009. So I don't know what's going on, I downloaded and used the patch from here: http://news.bitdefender.com/NW262-en--BitD...tion-Patch.html though the updates still won't work. 
Can someone please help me with this, thanks in advance.
