Test case won't run

I have a test case which reads input data from an input Excel file and uses data from each row to submit a request to a Web service. Once a response message is received, the data from the response message is transferred and written to an output Excel file so that I can examine each row. Typically, each row in the input Excel file will cause the response message to return a record from the database. However, on some rows in the input Excel file, the input parameters might cause the query to return no record.

I created this particular test case using soapUI Pro version 3.6.1 and it works fine. When a row of input data is used to submit input parameters that will cause no record to be returned. The corresponding row on the output Excel file will contain blank data and it will loop to read the next row of data. However, when I ran the same test case using soapUI Pro version 4.0.1, whenever it read the input data that would case the response message not to return a record back, the test case stopped. It wouldn't continue like when I was using soupUI Pro version 3.6.1. I tried to look around with different options but I could not figure out how to make it continue. Can someone tell me what I should do?

Thanks,
