Unable to access my Internet security unlimited

I had to do a recovery on my laptop,and wanted to install avg Internet security unlimited again  I then went to download Internet security unlimited from avg website but all it would download is the trial version. I had to 2 hours on line with tech help and they failed to solve the problem, when I log on to my account this is what is displayed;
