I am trying to install Internet Security 2016 using central.bitdefender.com with no success. I clicked on the "My Subscriptions", then on the "Activation Code" and I pasted my old activation code (with ~700 days left) and only got the message "The key you've entered is invalid". The "Install Bitdefender" button leads to Total Security installation with 30 days subscription(?!) Now on the "My Subscriptions" I have Total Security 2016 30 days trial. I don't need TS 2016! Now I have no Bitdefender product working on my computer. How can I remove my device account from Bitdefender Central?! (I can remove the device from my.bitdefender.com, but not from central.bitdefender.com). It's a complete mess...
