3D FlipBook - Purchased plugin, but can't find it.

Hi there,

I'm not sure about it now, but as far as I remember, I purchased FlipBook (I think 3 years ago, lifetime license). It seems I used it and it is stuck on version 1.10.14, I can't update to anything newer. Can you please verify if I have a license? Because I lost my emails that were before December 2021.

Thanks
