Problem with connection string addon

Hi,

I am using the following code in my program.cs

Application oApp = null;                if (args.Length < 1)                {                    oApp = new Application();                }                else                {                    oApp = new Application(args[0]);                }                Menu MyMenu = null;                MyMenu = new Menu();                oApp.Run();           

and this others lines are used to connect to SBO

   private void SetApplication()        {            SAPbouiCOM.SboGuiApi SboGuiApi = null;            string sConnectionString = null;            SboGuiApi = new SAPbouiCOM.SboGuiApi();           // sConnectionString = "0030002C0030002C00530041005000420044005F00440061007400650076002C0050004C006F006D0056004900490056";                       if (Environment.GetCommandLineArgs().Length > 1)            {                sConnectionString = System.Convert.ToString(Environment.GetCommandLineArgs().GetValue(1));            }            else            {                sConnectionString = System.Convert.ToString(Environment.GetCommandLineArgs().GetValue(0));            }            try            {                SboGuiApi.Connect(sConnectionString);            }            catch (Exception ex)            {                SBO_Application.StatusBar.SetText(ex.Message,BoMessageTime.bmt_Long,BoStatusBarMessageType.smt_Error);                System.Environment.Exit(0);            }            SBO_Application = SboGuiApi.GetApplication(-1);        }

I this give me in release mode after create my .ard file and installed in SAP B1 this error:

"attempt was made to reference a token that does not exist"

I debug it and this error occurs in this line:

SboGuiApi.Connect(sConnectionString);

what is wrong with my code?

Regards.
