jmail fejl. hvad kan der være galt?

Hej Alle. Jeg får følgende fejl når jeg prøver at køre jmail fra min side:

jmail.MailMerge error '8000ffff'

Mailmerge: Interface not supported. Invalid recordset

/soren/admin.updates.asp, line 103



her er koden.

<%
Elseif Request.querystring("mode") = "send" Then
response.write "<p><span class='topbox'>Vent venligst mens e-mails sendes:</span></p>" & vbCrlf

strSearchFor = ";" & Request.form("UpdateCategory") & ";"
strSql = "SELECT mail FROM list WHERE emne Like '%" & strSearchFor & "%'"

set msgTemplate = Server.CreateObject("Jmail.Message")
msgTemplate.Subject = "Hi Soren"
msgTemplate.Body = "Hello %%username%%. How are you today? Is %%useremail%% your real emailaddress? That's cool..."
msgTemplate.From = "me@whatever.com"
MsgTemplate.FromName ="mr Sender"
msgTemplate.AddRecipient "%%useremail%%","Soren"


    Set mMerge = Server.CreateObject( "JMail.MailMerge" )
    mMerge.MailTemplate = msgTemplate

    Set MyRS = rs.Execute(strSql)


-> dette er linie 103 mMerge.BulkMerge MyRS, false, "http://www.enhjemmeside.dk"

set msgTemplate = Nothing
set mMerge = Nothing

end if


hvad kan der være i vejen?
