Hi!! I am from India. I bought "Bitdefender Total Security 2012" from a retail store. But, then I got to know that 2013 edition is available to install using the 2012 license key. So, i didn't installed the 2012 version. And, installed the 2013 edition following the procedure given by you.
But, when I am entering my License key, it says "Invalid License key. Please enter another key".. What to do now?? Do I have to install the 2012 version?? Please help.. Currently, I am running on trial version of 2013 edition!!
