My computer came with the Antivirus 3.0 But since my license have expired, I can't upgrade it at all... so I tried to renew it (and I couldn't), even with the username and password I received on my email. I sent my email the username and password, incase if it's the wrong username and password, but I never received it. Then I uninstall the Antivirus so I can install it hoping it would fix again... but I couldn't install it back. I messed it up. Now I'm stuck with the trail version.
