In free edition i get the next messages :
system is not protected.
trial period has expired.
wait for bitdefender page to load (but it never loads)
microsoft .NET Framework : unhandled exception has occured in your application. If you click Continue the application will ignore this error and attempt to continue. if you click Quit the application will close. Value does not fall within the expected range.
I select continue and after a while i get the same message from MyBitdefender.
I asked for a Free key and received but dont know what i can do with it.
Thanks for your time.
