RunTime Error

i implemented my Application using Com+, i'm getting this error:Run time error "3251": ....etc.
i checked this link:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q201716.
and i checked my code it contains the following:

Private Sub ObjectControl_Activate()
Set Cnn = New ADODB.Connection
Set Cmd = New ADODB.Command
On Error GoTo Err_Cnn
    Cnn.Open connstr
Exit Sub
Err_Cnn:
   ChkVal = 1
Set mV2 = GetObjectContext()
  End Sub


Public Function OpenRecordSet(spName As String, ParamArray AttachedParameters() As Variant) As ADODB.Recordset
'Dim MyRec As ADODB.Recordset
Set Rs = New ADODB.Recordset
Dim i As Long
If Rs.State = adStateOpen Then
   Rs.Close
End If
With Rs
    .CursorType = adOpenKeyset
    .LockType = adLockOptimistic
    .CursorLocation = adUseClient  '<-- Add this line
End With

On Error GoTo ERRORHANDLER
     Cmd.CommandTimeout = 3600
     Cmd.ActiveConnection = Cnn
     Cmd.CommandType = 4 'Stored Procedure
     Cmd.CommandText = Trim(spName)
        If UBound(AttachedParameters) >= 0 Then
            Cmd.Parameters.Refresh
            For i = 0 To UBound(AttachedParameters)
                Cmd.Parameters(i + 1).Value = AttachedParameters(i)
            Next i
        End If
     Rs.Open Cmd
     Set OpenRecordSet = Rs
     Exit Function
ERRORHANDLER:
    Set OpenRecordSet = Nothing
    End If
End Function

Private Sub ObjectControl_Deactivate()
    Set Cnn = Nothing
    Set Cmd = Nothing
    Set Rs = Nothing
    Set mV2 = Nothing
End Sub
........ i tried to comment the deactivate Sub as to keep the record connected but still i'm getting the error:-(
Any Help!!!!!
