New affiliate User registration is not a success

Started using the Coupon Affiliate Pro free trial but, when registering a new user as an affiliate the new registrations display as users as a coupon affiliate but the vouchers are not assigned. even if we tried editing manually it cannot be done since the editing does not display the vouchers as the documentation. The new registrations are not displaying under Approvals. That means there is no approval process even if we undo the auto-acceptance of new registrations.
