Hi,
Please check the "Restriction" part of the Authorize payment configuration.
You also have to check that the payment plugin is enable and the payment configuration is published.
HikaMarket adds some options for the payment plugins too, you have to verify that you did not assign a vendor to the payment method.

By the way, do not send me private message, use the "contact us" form instead.
