paypal error when not using paypal ("Secure Hosting")

Hi I have Zencart v1.3.9h installed and it appears to be working OK until we try to go to checkout. I have set up a payment module with secure hoting to accept credit cards, this works well, the customer is forwarded to SecureHostings site to make the payment. I have disabled all other payment options including Paypal as the owner only wants to accept payments via Secure Hosting.

When the customer gets to checkout he fills in all his details and clicks to process the order. The order gets processed but the customer is returned to an error page on my site with the message below. I have seen this message on other posts but it always refers to people trying to pay with Paypal which as I say on my site is disabled.
Can anyone tell me how to get of this please
Here is the message

1054 Unknown column 'zen_order_id' in 'field list'
in:
[INSERT INTO paypal (zen_order_id,txn_id,payment_date,payer_id,reason_code) VALUES ('16','39967969','2011-02-10 11:37:07','','Success')]

Sounds like your "SecureHostings" payment module that you've installed was probably modeled after the paypal module, by copying its code and hacking it up to work with another gateway ... but the hacking wasn't thorough enough.
Suggest you contact whoever wrote your module and ask them to sort it out.
