DUMLdore crash when loading custom firmware - System.ArgumentOutOfRangeException

[dol1234]

Hello
When flashing Spark with Latest battery MOD from @brett8883 DUMLdore silently crash. I found following error in event log.

Aplikacja: DUMLdoreV3.exe Wersja architektury: v4.0.30319 Opis: proces został przerwany z powodu nieobsłużonego wyjątku. Informacje o wyjątku: System.ArgumentOutOfRangeException w System.Windows.Forms.Control.MarshaledInvoke(System.Windows.Forms.Control, System.Delegate, System.Object[], Boolean) w System.Windows.Forms.Control.Invoke(System.Delegate, System.Object[]) w DUMLdoreV3.ControlExtensions.SafeInvoke[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]](System.Windows.Forms.Control, System.Func'1<Int32>) w DUMLdoreV3.Form1.UpgradeStatus(Duml.Msg) w Duml.MsgParser.HandleIncomingMsg(Duml.Msg) w Duml.MsgParser.ReadFromPort(System.Object) w System.Threading.ThreadHelper.ThreadStart_Context(System.Object) w System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean) w System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean) w System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object) w System.Threading.ThreadHelper.ThreadStart(System.Object)

Latest version of DUMLdore was used (downloaded directly from GitHub). I was able to flash Spark with official firmware. Checked on two different windows 10 x64 machines and cable sets.
It would be great if you could take a look into this issue, thank you.
