Failed to Install and Activate AVG TuneUp

I have recently been automatically invoiced and have paid for a new 1 year AVG TuneUp subscription. I already have AVG Internet SAecurity enabled.On my account page there is an option to Install and Activate, but each time I attempt it, I get a separate box that runs for several seconds and then returns a "Failed" message.

Any ideas why?

P.s.

The subscription renewal email, for AVG TuneUp did not supply a separate activation code.
Also I get options from AVG Internet security, whilst scanning to get a licence for AVG TuneUp, which is ironic as I have pad for the service!
