The rewarded ClAIM does not respond

Avast Free Antivirus / Premium Security

Hello there,
I invite friends to use AVAST, therefore rewarded,
But the reward ClAIM button does not respond,
So the activation code cannot be obtained,
How do I get the activation code?

Hopefully someone with experience on the Rewards program will respond, until then see this:
