Hello.
I had purchased Bitdefender 2012 like 6 months ago. I saw a post on the forum that it can be upgraded to 2013 and I did so. Till now I was running bitdefender 2013 on Windows XP SP3. Recently I purchased a new RAM and installed windows 7. I tried installing bitdefender 2013 but it will not accept my key again. My key is valid for another 165 days and I want to use it. Till now I had thought that while registration of the product bitdefender main server remembers the MAC ID of the installed computer. Can someone help me with this issue? I want to use bitdefender 2013 again. Please dont confuse it. I am installing it on the same laptop that I installed it the first time. Please help me with this.
