XFileSharing Pro - Payment Gateway desperate help with this mod

[israel]

Hi, i just bought the plugin "Payment Gateways" I uploaded every file by FTP to their place but i cannot see the payment gateways bytsellers, Stripe etc. under settings / Payment Settings I only can see Paypal there. Am I missing something? Do I have to activate the plugin some where? I've been stuck with this for the last 4 hours, I don't know what to do.
