Closed discount option, how to get it back?

Hi,

I flew through Schiphol last week and I saw that F-Secure Freedome was their VPN of choice. I decided to download the client and run the trial period, of which I was very satisfied. When it was 1 day from the end, a popup appeared to remind me to start a new subscription, with promo code of 29.99$ instead of 59.99$. I was at work, so I closed it, pretty sure that I could go back again later from home. Unfortunately, that didn't happen.

Is there a way to get this popup back? I liked the service and I would like to subscribe, especially at those price.

Thanks for the help
