fejl i åbning af database

Jeg får en fejl på denne kode:

<%
if request.querystring("mode") = "insert" then
    ' ADODB connection objektet
    Set Conn = Server.CreateObject("ADODB.Connection")
    DSN = "DRIVER={Microsoft Access Driver (*.mdb)}; "
    DSN = DSN & "DBQ=" & Server.MapPath("../../../../cgi-bin/statistik.mdb")
    Conn.Open DSN
    ' Indsæt i statistik
    strSQL = "insert into statistik (playername, mynumber, counter) values('" & Request.Form("playerName") & "', '" & Request.Form("theNumber") & "', '" & Request.Form("counter") & "')"
    ' Luk databaseforbindelse
    Conn.Close
    Set Conn = Nothing
    response.redirect "statistik.asp"
else
%>

fejlmeddelelsen er:

Error Type:
ADODB.Connection.1 (0x800A0BB9)
The application is using arguments that are of the wrong type, are out of acceptable range, or are in conflict with one another.
/carsten/htx/teknologi/uge1-9/Guess_Number_beta1.asp, line 9

line 9 = Conn.Open DSN << men det stammer nok fra en foregående linie...
