Payment methods Disputes give mistakes with nitrous

Question

Need help from someone more familiar with Spree and / or Zakis than me.

I recently transferred my work to the Spree store website from my mac (which died) to a PC via Nitrous (I received the files that I transferred to Github). After many new errors caused by loading these seeds, I worked on all the bends during the transition, except for one. I tried to go through the verification process, but none of the methods that I added seem to work, and the option for credit cards is not available.

I went to add several payment methods to make a choice order for another application I'm working on, and the following list of all available payment options:

Spree::BillingIntegration::Skrill::QuickCheckout
Spree::Gateway::AuthorizeNet
Spree::Gateway::AuthorizeNetCim
Spree::Gateway::BalancedGateway
Spree::Gateway::Banwire
Spree::Gateway::Beanstream
Spree::Gateway::Bogus
Spree::Gateway::BogusSimple
Spree::Gateway::BrainTreeGateway
Spree::Gateway::CardSave
Spree::Gateway::DataCash
Spree::Gateway::Eway
Spree::Gateway::Faxibra
Spree::Gateway::Linkpoint
Spree::Gateway::Maxipago
Spree::Gateway::Migs
Spree::Gateway::Moneris
Spree::Gateway::PaypalGateway
Spree::Gateway::PayflowPro
Spree::Gateway::Paymill
Spree::Gateway::PinGateway
Spree::Gateway::SagePay
Spree::Gateway::Samurai
Spree::Gateway::SecurePayAU
Spree::Gateway::StripeGateway
Spree::Gateway::UsaEpay
Spree::Gateway::Worldpay
Spree::PaymentMethod::Check
