Hello, Jack,
I apologize for all of the inconvenience.
We close the business, and we will no longer support products.You do not have to pay again for the products you bought before. All your files are yours. All of them you can download until 18th October. But if you still want to get support and updates of Gavick's products you can take advantage of the Joomlart offer.
More information you can find here:
