RobotStudio event

Event log Return OverTime

Hi Guys:

Recently ,I met a problem as follow:

When I try to read the system message use C# by PCSDK, it return the error like this

"function calculate overtime " "Because of  function calculating overtime ,function calculate was forbidden ",Then I try to read the others message ,but return the same

my code like this :

        private EventLog mCurrentEvent = GudData.mController.EventLog;
        private void CmdUpdataMessage_Click(object sender, EventArgs e)
        {

            EventLogCategory wMessage= mCurrentEvent.GetCategory(CategoryType.System);
            EventLogMessage msg = wMessage.Messages[1];
        }

I'm sure there are two message in wMessage,

 does someone can help me ?

Thanks
