I purchased Bitdefender Total Security 2016 yesterday, activated it as per your email, and downloaded it from Bitdefender Central. I then installed it, updated it, and ran a scan. Today I have turned on my computer and instead of the red icon in my system tray, there is a greyed out icon displaying the message that I need to sign in to activate my copy of Bitdefender. However, when I launch the program, I can see my name, and all looks as it did yesterday. The top right menu shows my name, and clicking the links takes me to my account on Bitdefender Central. I can run a scan, and I can see that I have 365 days left of my current subscription. There is no link anywhere requiring me to sign in, and no link anywhere requiring me to activate anything again. i am concerned that the software is now doing nothing to protect my system as the icon is greyed out and I cannot take any action to change it or the message about having to sign in. It is not a reassuring start to my first ever use of software from this company.
