Hi, I have an active Bitdefender 2010 Key. I tried to put that code on the Bitdefender Central in order to get a 2016 suscription. The problem is that every time that I try to do so, Central says that my key is invalid (but it works perfectly and it's valid). So, due to this problem I can't transform my Bitdefender 2010 key into a 2016 suscription.
Anyone knows how to do this?
