Bitdefender 2010 Total Security Window Is Not Loading

Well, I have Bitdefender Total Security 2010, and it was perfectly functioning, until I used Bitdefender to download critical updates and after installing and restarting, when I right clicked the bitdefender icon on the taskbar and then show, the window doesn't come up. When I choose any other option in the menu, it doesn't work and while the update window loads, it just keeps loading... I tried all the advice on this page:

What should I do to resolve this?

Thanks!
