Error trying to Import from a TXT File with a XMLPort

Is the first time i use xmlports, so maybe something is wrong.
Error appears when I execute codeunit that calls the XmlPort.

"Error configuring XML analizer
Error = c00cee2d Code meaning=Unknown error 0xC00CEE2D"
Any idea about how to solve that?

Another question: Is possible to call the xmlport, and show a requestform to ask for the file path, without using a codeunit?
Thank you very much.

Just some context to suport the question

I´m using W.vista
Executing from Clasic Client 6.0


I Create the codeunit:
57100 "UPload TXT File"

With this code:

OnRun()
BEGIN
    IF ISSERVICETIER THEN 
      BEGIN
          IF UPLOADINTOSTREAM('Select File:','C:\Temp','TXT File *.txt| *.txt',ClientFileName,TestStream)
            THEN MESSAGE('Uploaded File')
          ELSE
              EXIT;
      END
    ELSE 
      BEGIN
        TestFile.OPEN('C:\Temp\N43.txt');
        TestFile.CREATEINSTREAM(TestStream);
      END;
     XMLPORT.IMPORT(57100,TestStream);
    IF NOT ISSERVICETIER THEN TestFile.CLOSE;
END;

Then I create XMLPort, 57100 with this definition
that read one row and then i split the row to fill fields.
