Atos Payment Processor

Hello!

I'm setting up my cs.cart store. My previous store used the Atos Payment Processor.

I followed step-by-step the Atos tutorial provided by cs.cart, and when clicking the "Pay" button while doing an order, a new page opens and says:

"Connecting to Atos server..

API ERROR

Error reading merchant parameters definition (/home/www/app/payments/atos_files/parmcom.xxxxxxxxxxxxxxx)

"

Is this a common error, is there any "quick fix"?

I did exactly as cs.cart told me to do, to the letter.

Thank you!!!
