problemer med SAfileUp

Jeg har følgende kode:
--------------
Set Upload = Server.CreateObject("SoftArtisans.FileUp")
Upload.Path = server.mappath("../Profil_billeder/")
strFilename = Upload.Form("file").UserFilename
strFileExt = Mid(strFilename, InstrRev(strFilename, ".") + 1)
If Upload.TotalBytes > 200000 Then
    intErrorCode = 21
ElseIf    LCase(strFileExt) <> "jpeg" AND LCase(strFileExt) <> "jpg" AND LCase(strFileExt) <> "png" Then
    intErrorCode = 20
End If

If Not Upload.Form("file").IsEmpty And intErrorCode = 0 Then
    strFilename = session("UID") &"_"& strFilename
Upload.Form("file").SaveAs strFilename
-------------

Og jeg får følgende fejl:

----------------
Error Type:
SoftArtisans.SAFile.1 (0x8007007B)
Error occurred when moving cached file to final destination. Please check the NTFS permissions for the directory "D:\IIS\moejensen\_ny\Profil_billeder" and the directory containing the file "63_Z:\2 Billeder\billeder af mig\små\IMG_3800.jpg". These directories require Read, Write and Delete permissions by the anonymous user ( NT account: IUSR_computername ) and/or by your authenticated users.The filename, directory name, or volume label syntax is incorrect.
------------------

Men jeg har sat rettighederne på profil_billeder. Hvad kan der være galt
