AVG Pro 30 day trial

Hello Keith,
We apologize for the inconvenience caused.
We like to inform you that AVG Zen is just the user interface to  manage your AVG Product?
Are you wish to continue with AVG free or want to purchase AVG Pro paid version?
Unfortunately, from your recent message, it was not clear to us how we can help you. Could you please specify your request and provide us with more details? Thank you for understanding. We look forward to hearing from you soon.
Thank you.

I wish to continue with AVG free.

I accidentally let AVG Pro run for 30 days for free and now the program wants me to purchase AVG Pro but I want to run AVG Zen and after the download a window blocks me from running Zen. Again how do I get around AVG Pro purchase?
