First, when I clicked on the button to download for Windows, it said it was working, but I kept waiting and waiting and waiting and waiting. Meanwhile, when I clicked on the Activation Code it said that the code “This key was already used to generate a subscription.” So now I have this software on my mobile phone but no code to make it last longer than 10 days, and NO software on my PC. This is extremely annoying, especially since the main reason I wanted this was to hope that hte upgrade woudl get rid of the “a problem has occurred in BitDefender Threat Scanner” message I get whenever I boot up my system after the original installation of BWD.
