I downloaded the trial version of NOD32 AV. I am currently using 4.0.437.0 which I assume is the latest version. My trial has expired, so I went and bought a 2 year licence. I clicked on 'Upgrade to full version' and entered the details I recieved after purchasing, clicked OK and nothing happened. About ten minutes later I decided to restart. Now whenever I click 'Upgrade to full version', the clock timer icon appears next to 'Update', so I assume it is doing something, but it just goes on forever and nothing happens. I have disabled my firewall (Online Armor) but the same thing happens. When OA is running, NOD32 is completely allowed and trusted. Any way to get it to upgrade without a reinstall? EDIT: Nevermind, tried it again and went and had a shower and it was upgraded when I got back. Guess it just takes a while.
