PublishFromNWFXml always getting the error: "... Index was outside the bounds of the array."

[#1]

I am using the workflow.asmx webservice and I always get the following error: "Error returned from server: soaperverServer was unable to process request. ---> Index was outside the bounds of the array." when using the PublishFromNWFXml method.

I have used the procedure to copy and publish workflows by Mr Paylor and also the .pdf here on line. I have used regex and replaced special characters.

What is happening here?

Thanks.

Aloha,

Problem Fixed.

I did not recognize that the WorkflowFile parameter was not supposed to be the URL,

but the actual contents of the file. Thank you for all your help and patience.
