ISoapFormatter - System.Xml.XmlException: The root element is missing

[Frederico Guimar?es via DotNetMonster.com]

Hi,
I'm trying to use the Microsoft.Web.Services2.Messaging.
ISoapFormatter

but I receive this error:
System.Xml.XmlException: The root element is missing.
at System.Xml.XmlTextReader.Read()
at Microsoft.Web.Services2.Xml.XmlSkipDTDReader.Read()
at System.Xml.XmlLoader.Load(XmlDocument doc, XmlReader reader, Boolean
preserveWhitespace)
at System.Xml.XmlDocument.Load(XmlReader reader)
at Microsoft.Web.Services2.SoapEnvelope.Load(Stream stream)
at
Microsoft.Web.Services2.Messaging.SoapPlainFormatter.Microsoft.Web.Services2.Messaging.ISoapFormatter.Deserialize
(Stream stream)
at WebSemantica.SoapSmtp.Mailbox.EndReceive(IAsyncResult result) in c:\
wsf-projeto+final-julio\wsf-projeto final\websemantica\zutil-soapsmtp\
mailbox.cs:line 307
----------------------------------------------------------
the code I'm using is (line 307 is the last line):

UTF8Encoding encoding = new UTF8Encoding();
SimpleMailMessage m = messagesArray;
ISoapFormatter formatter = new SoapPlainFormatter();
MemoryStream stream = new MemoryStream( encoding.GetBytes( m.TextDataString
) );
envelopes = formatter.Deserialize( stream );
----------------------------------------------------------
if I print the xml (the "m.TextDataString") the result is:
<?xml version="1.0" encoding="utf-8"?>
