Respectfully, I have two bitdefender Internet Security license keys, two per one-for one PC , two days ago when I was going to upgrade to that 2016 one, I saw that I was not able to add one of my license keys to my subscription, after downloading the BIS told me that my subscription is terminated!!meanwhile it has over 305 days left; I saw only one license keys(one of the two license keys) and so one of my PC is without BIS at this present, in addition to , today I faced other problem in this sense I am not able to login to my Bitdefender central account, after giving email and password I face a white page and the login page window comes back again with the following link:
https://login.bitdefender.net/?redirect_url...rror=unavailabe
passing two days but the Bitdefender has not responded me to solve the above problems yet.
