Web Service; Error attempting to read from file

Question

I'm trying to connect to a web service as outlined by the book "Creating Dynamic Forms with Adobe LiveCycle Designer" which is an excellent book by the way.
I'm receiving the following error "Error attempting to read from file. http://www.webservicex.net/BibleWebservice.asmx"
I've successfully created the Data Connection to
http://www.webservicex.net/BibleWebservice.asmx?wsdl
I dragged and dropped the bookTitle, chapter & Versie onto the form. I also dragged and dropped the GetBibleWordsByChapterAndVerseResult and the GetBibleWordsByChapterAndVerseBtn.
I Preview PDF and click the button I get the above error.
Does anyone have experience using Web Services with Adobe LiveCycle ES and have advice on how to resolve this. Any Suggestions would be greatly appreciated.

Well, I have more news on the error I'm getting. - NO I didn't find the problem. Yet
I checked and made sure that web.config had "None" selected " in authentication mode. I.E. <authentication mode="None" /> This should eliminate any authentication problems since that turns off IIS's authentication checking.
At first I was thinking the form was generating the error trying to read the result coming back from the web service, but I put in some code that writes the result to a log file when the method fires off.
I noticed that when I clicked on the button on the form, the error message would pop up from Acrobat, but when I check the log file, there was NO entry. This means that Acrobat failed before it could execute the method.
Here is the web method:
[WebMethod(CacheDuration = 30,
Description="Returns the String 'True' or 'False' whether or
not you entered a 'T' or 't'.")]
public string TF(string Tf)
string result="False";
if(Tf.Substring(0,1).ToLower()=="t"){
result= "True";}
LogFile.Write("Sent: "+result);
return result;
