Consuming WebService to Place an Order and Authorize Card

I am running into an error when I make a call to the CCProcessCard using the
WebService. The Web Service call returns an error of "Invalid Order" same
error when using the WSTester. So I used the BO tracing and entered an order
and Authorized the Credit Card which works.

My next test was to enter an order using the Web Services and then use the
BO to try and run the CCProcessCard or Authorize button. This returns an
error of: "operable program or batch file"

I have compared the SalesOrderDataset from the order entered in BO with the
one entered with Webservices and they match. Herein lies my confusion. Does
anyone know what this error means or have any ideas for further
troubleshooting ?
