Error: Overload resolution failed

[Eph0nk]

Hi,

I get an overload resolution failed error (Overload resolution failed because no accessible 'New' can be called without a narrowing conversion), and I can't seem to find a lot of relevant information by googling the web.
Function GetFromXml(Id As String, Node As String)
Dim NodeValue As String
Dim xpathDoc As XPathDocument
Dim xmlNav As XPathNavigator
Dim xmlNI As XPathNodeIterator
xpathDoc = New XPathDocument(Getpath() & ArticlesXmlFile)
'------- ^^^^^^^^^^^^^^^ ERROR IN LINE ABOVE'
xmlNav = xpathDoc.CreateNavigator()
xmlNI = xmlNav.Select("/articles/article[id=" & Id & "]/" & Node)
While (xmlNI.MoveNext())
'Response.Write(xmlNI.Current.Name + " : " + xmlNI.Current.Value & "<br>")
NodeValue = xmlNI.Current.Value
End While
Return NodeValue
End Function

The GetPath() function just returns the path under the current - the path it returns is checked & is correct (the function gets used in other places without error), only when i call it in this "xpathDoc = New XPathDocument()" part.
If i enter the path manually (XPathDocument(PATH_HERE)) everything works find.

Any idea what causes this? The complete error message is listed below:
