I have seen this kind of thing before. As I understand it xAPFramework
apps don't directly relay messages but pull them apart at receipt and
rebuild them for sending. This is why the order of elements can change.
This also has the side effect of stripping of some odd characters from
the ends of lines. I have made messages that wouldn't pass through a hub
but if you opened the up in viewer and hit resend it worked, that time I
had used a vbcrlf instead of a chr(10) at the end of a line.

A very simple vb code for sedning a message would look like this:
xapmessagebody = "xap-header" & Chr$(10) & "{"
& Chr$(10)
xapmessagebody = xapmessagebody & "v=12" & Chr$(10)
xapmessagebody = xapmessagebody & "hop=1" & Chr$(10)
xapmessagebody = xapmessagebody & "uid=FF" & xAPUID &
"00" & Chr$(10)
xapmessagebody = xapmessagebody & "class=xAP-OSD.Display"
& Chr$(10)
xapmessagebody = xapmessagebody & "source=mi4.weather." &
xx & Chr$(10)
xapmessagebody = xapmessagebody & "}" & Chr$(10)
xapmessagebody = xapmessagebody & "Display.Tivo" &
Chr$(10)
xapmessagebody = xapmessagebody & "{" & Chr$(10)

xapmessagebody = xapmessagebody & "Text=Outside temperature is
" &
tmp & " Wind is " & wnd & " " & winddir
& Chr$(10)

xapmessagebody = xapmessagebody & "Duration=30" & Chr(10)
xapmessagebody = xapmessagebody & "}" & Chr$(10)
xapudp.SendData xapmessagebody

where xapudp.  is the winsock control.  It would be worth double checking :
That every line ends in a chr$(10)
That if the Source= line contains a :  that the uid doesn't end in a 00
That if the Source= line doesn't contains a :  that the uid does end in a
00
