My site consists of products ( patterns to make certain things), that the customer needs to purchase in a group and have need to purchase every 30, 60 or 90 days in order to download the patterns.

Having a hard time finding a method to set this up, without canceling the customer.

Would appreciate any help that I can get

(ZenCart V1.3.7) currently no addons and just starting with the basic page.
