[DataChanger] LF2 IDE v3.4.0

[NightmareX1337]

I have problem with your data changer. It worked perfectly, but now when I try to open a .dat file, or just only program, it crashes and gives this error:

Spoiler (Click to View)

Code:

System.InvalidOperationException: The dock state is invalid.
   w WeifenLuo.WinFormsUI.Docking.DockContentHandler.SetDockState(Boolean isHidden, DockState visibleState, DockPane oldPane)
   w WeifenLuo.WinFormsUI.Docking.DockPane.RefreshStateChange(INestedPanesContainer oldContainer, DockState oldDockState)
   w WeifenLuo.WinFormsUI.Docking.DockPane.InternalAddToDockList(INestedPanesContainer container, DockPane prevPane, DockAlignment alignment, Double proportion)
   w WeifenLuo.WinFormsUI.Docking.DockPane.DockTo(INestedPanesContainer container, DockPane previousPane, DockAlignment alignment, Double proportion)
   w WeifenLuo.WinFormsUI.Docking.DockPanel.Persistor.LoadFromXml(DockPanel dockPanel, Stream stream, DeserializeDockContent deserializeContent, Boolean closeStream)
   w WeifenLuo.WinFormsUI.Docking.DockPanel.Persistor.LoadFromXml(DockPanel dockPanel, String fileName, DeserializeDockContent deserializeContent)
   w WeifenLuo.WinFormsUI.Docking.DockPanel.LoadFromXml(String fileName, DeserializeDockContent deserializeContent)
   w LF2.IDE.MainForm..ctor(String[] args)
   w LF2.IDE.Program.Main(String[] args)

I can't reproduce this, can you try the debug build and show me the error message? You need to give a lot more info than this if you want me to really sort it out.
Meanwhile you can delete %AppData%\docking.xml as a workaround.
