As per your response to the private message sent to me today, I am starting a new thread.
Apparently in common with many others, BD frequently greys out and stops respnonding with no error message. Essentailly always, scans fail part way through with a message that BD has stopped responding.
The support tool , when run manually as per many other posts, does not show any progress after 2+ hours.
Now that I have complied with your apparently automatic response to my message, I would appreciate some support.
