Hi guys Think I screwed up config on Instant Sheller and now it is stuck. Basically Windows is not shelled, the programme only boots back to the undo button though. When I try to undo it gives me the below error. I think that some parts of the shell worked and some didn't so now it thinks it needs to reverse changes. Basically i just want to be able to run it again fresh, can anyone help at all? ************* Exception Text **************System.IndexOutOfRangeException: Index was outside the bounds of the array. at c.h(Object A_0, EventArgs A_1) at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Thanks Tom
