So...everyone thinking 'all she has to do is say she forgot the password and get a new one' ? That's exactly what I couldn't do.
What I did have to find was a way to remove the AVG Secure Search so I that I could do that. (This appeared when I updated the AVG.) Right click on the AVG logo on the bottom bar and you can remove it for 10 minutes. Now that's useful!
But I wish I had known it an hour and a half ago - or this morning!
