Probleme mit Umsetzung auf 64 Bit

Thorsten
ich habe vor einiger Zeit ein umfangreiches Tool unter Excel 2007 (32 Bit) in VBA entwickelt, u.a. mit FTP-Zugriffen. Den Code für die FTP-Funktionalität habe ich damals hier 1:1 entnommen:
http://www.office-loesung.de/ftopic154081_0_0_asc.php
Funktionierte bisher alles bestens. Vor ein paar Tagen habe ich auf meinem PC Excel 2013 (64 _ Bit) installiert und habe mit Erschrecken festgestellt, dass das Tool unter 64 Bit nicht läuft! Ich beschäftige mich jetzt schon seit einigen Tagen intensiv mit dem Problem, aber lösen konnte ich es noch nicht. Ich habe allen "Declare" ein PtrSafe hinzugefügt und alle Handles und Zeiger vom Typ Long in LongPtr konvertiert. Excel beendet sich immer in folgender Funktion beim Aufruf von
MoveMemory IPArray(0), ByVal pIP, 4
Private Function IPAdresse(ByVal Adresse As String) As String
Dim pAdresse As LongPtr, AdresseInfo As HOSTENT
Dim pIP As LongPtr, IPArray(3) As Byte
Dim WSADaten As WSAData
WSAStartup &H202, WSADaten
pAdresse = gethostbyname(Adresse)
If pAdresse = 0 Then
IPAdresse = 0
Exit Function
End If
MoveMemory AdresseInfo, ByVal pAdresse, Len(AdresseInfo)
MoveMemory pIP, ByVal AdresseInfo.haddrlist, 4
MoveMemory IPArray(0), ByVal pIP, 4
WSACleanup
IPAdresse = IPArray(0) & "." & IPArray(1) & "." & IPArray(2) & "." & IPArray(3)
End Function
Ich weiß keinen Rat mehr :(. Ich hoffe dass mir hier irgendjemand helfen kann, bin dankbar für jeden Hinweis! Danke schon mal im Voraus!
