Im having the same issue. It keeps saying 30 day trial.
Tryed just about everything. Was told to remove windows live family security.
also removed prey from www.preyproject.com as it may have conflicted with BD2013.
Uninstalled plus used the uninstall tool and cleaned the registry.
But nothing, also doesnt do anything after the update.
Keeps saying trial license, and it wont login to mybitdefender from the application either. But login works just fine from the website.
Can i get another key too ive spend about 2 half days trying to fix this and its not working.
