Getting Driver Updater to open and download

This morning I paid and was sent a download email. When I clicked on the download button the process starts and a few seconds later stops and says "FATAL ERROR" I have treid this several times without success. Can anyone help. I also tried to have a chat online but no one on the other end.

Hello Alan,
It seems you have received old/previous AVG Driver Updater installer link.
You can click here to download AVG Driver Updater installer, run the downloaded file and install it. After that, you can open the installed AVG Driver Updater, click on support button > Enter registration Key to activate it.
Cheers,
Alok.
