WHMCS Payment Gateway Error

I have an older version of WHMCS Web Hosting and Account Management script. It continues to give Credit Card not valid error, although credit cards are fine when processed manually. Some expert in debugging WHMCS [url removed, login to view] It only happens with [url removed, login to view] and none of the other payment gateways. Have reset transactions keys, etc. still no work. Only those experienced with WHMCS and debugging these issue, please apply.
