Hi,
I have installed Bitdefender Internet Security on two PC's one with Windows 7 64bit (premium) and one with Windows 8.1 64bit (Pro) and only my PC with Windows 7 is appearing as a device on the My Bitdefender Dashboard. I have tried uninstalling and reinstalling several times on the Windows 8.1 version and logging in via Bitdefender, and I am unable to see the registered device on the dashboard? Any thoughts?
