Renewing avg when you have lost everything after my hard drive was replaced

I have a monthly subscription to AVG via a South African ISP. After my hard drive crashed and was replaced, I need to reinstall AVG Internet Security to use what I am already paying for. I have the license key. I don't want to take out a new subscription. How do I reconfirm my subscription?

Hello Roger,
We understand you would like to reinstall AVG. We see from your record that you have active subscription for AVG PC TuneUp. You can install this product from this link http://files-download.avg.com/inst/mp/AVG_PCTuneUp_765.exe and activate the product using the license number you have.
Thank you
