-If you get an invalid license error, check lib/license.php has the right license. 
If it still gives an error, reissue from your PTCPay client area.

-To purchase add-ons, you can go to the store, click order, select the GeN4 script, 
check the add-ons at the bottom, click add to cart, remove the script from your cart
and just checkout the add-ons.
