Thank you.

I have a trial version of AVG Protection, and I am trying to setup a Zen Network. I installed AVG via AVG Zen on both my computers, but now the AVG client on both is giving me this popup window:

AVG is not able to recognize your License Number.

However, I do not have a license number, because AVG Protection doesn't need one (from MyAccount->Subscriptions):

License number:
There is no license number for AVG Protection PRO.
To activate, simply open it and log in using your AVG MyAccount email and password.

Ok.... so how do I setup AVG through Zen?
