Hi! About a year ago, we purchased three regular licenses (for 3 sites) for the 3D FlipBook WordPress Plugin Pro Edition, the first purchase was from Envato, the last two from gumroad.com. Envato is now nagging us to "Extend support for $18.75". How long does support last with a Regular license?
What is the difference between the Regular vs. Extended licenses?
Will I be offered to extend support for my gumroad.com licenses and if so, how much will that be?
Anything else you can tell me about licensing and support?
