Woocommerce Authorize.net CIM plugin not allowing subscription purchases! -- 2

***FREELANCER MUST BE EXPERIENCED WITH [login to view URL] ISSUES*** I just got a new merchant account and use [login to view URL] for my gateway. My website sells subscriptions as well as products. I installed the [login to view URL] CIM plugin and an SSL cert to start taking payments without using PayPal. The payments work fine when customers buy PRODUCTS, however when they buy SUBSCRIPTIONS the payment will not go through. There is an error message stating the customer needs to use an alternate form of payment. I called [login to view URL] and they said the issue must be on my end. I need a freelancer experienced in this area to help fix this issue. GThanks.
