There a lot of System.FormatException in the log file because culture is not very well managed in Elephant I think.

A very easy way to fix that is to use such a function (VB.NET)

    Public Shared Function ToDecimal(ByVal number As String) As Decimal
        Dim StringSeparator As String
        StringSeparator = System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator

        If StringSeparator = "," Then
            Return Decimal.Parse(number.Replace(".", ","))
            Return Decimal.Parse(number)
        End If
    End Function

Please inform your developers.
