aquamail unlocker not working

[ZettBee]

Hi there,
On 14 januari 2016 I purchased the unlocker. Now I have a new phone and used a backup from my old phone to reinstall all the apps but the unlocker isn't working. I checked Google Play for the unlocker but I have to pay again? This is probably caused by my gmail account change a few months back. I can't access my old gmail account anymore and I can't find the unlocker app on my old phone. How can I get the unlocker again?
Thanks.
