Trying to run a program(doesn't work)

Hello,

I have just recently started working with EV3 and monobrick.
Up until now everything was working well, I managed to boot the monobrick through the SD
and managed to run a few of the example programs.
However when I wrote my own program and transfered it using USB cable and the WINSCP program, the program in the EV3 says it is running but a second after it returns back to the program manu in the brick.

I though it might be the way I transfered the exe and the dll but when I downloaded an example program from the brick and upload it again with a different name it ran ok.

the examples i have tried are:

using System;
using MonoBrickFirmware;
using MonoBrickFirmware.Display;
using MonoBrickFirmware.UserInput;
using MonoBrickFirmware.Sensors;

using System.Threading;
namespace ev3test
{
class MainClass
{
public static void Main(string[] args)
{
LcdConsole.WriteLine(“Hello World!”);
System.Threading.Thread.Sleep(10000);
}
}
}

and

using System;
using MonoBrickFirmware;
using MonoBrickFirmware.Display;
using MonoBrickFirmware.UserInput;
using MonoBrickFirmware.Sensors;

using System.Threading;
namespace ColorSensorExample
{
class MainClass
{
public static void Main (string[] args)
{
EventWaitHandle stopped = new ManualResetEvent(false);
ColorMode[] modes = {ColorMode.Color, ColorMode.Reflection, ColorMode.Ambient, ColorMode.Blue};
int modeIdx = 0;
var sensor = new EV3ColorSensor(SensorPort.In1);
ButtonEvents buts = new ButtonEvents ();
LcdConsole.WriteLine(“Use color on port1”);
LcdConsole.WriteLine(“Up read value”);
LcdConsole.WriteLine(“Down raw value”);
LcdConsole.WriteLine(“Enter change mode”);
LcdConsole.WriteLine(“Esc. terminate”);
buts.EscapePressed += () => {
stopped.Set();
};
buts.UpPressed += () => {
LcdConsole.WriteLine(“Sensor value: ” + sensor.ReadAsString());
};
buts.DownPressed += () => {
LcdConsole.WriteLine(“Raw sensor value: ” + sensor.ReadRaw());
};
buts.EnterPressed += () => {
modeIdx = (modeIdx+1)%modes.Length;
sensor.Mode = modes[modeIdx];
LcdConsole.WriteLine(“Sensor mode is set to: ” + modes[modeIdx]);
};
stopped.WaitOne();
}
}
}

some more technical stuff:
I am using Visual Studio 2010 and I run the program in my computer, the commands throw exeptions all the time and then I transfer the exe and dll in the debug folder of the program i ran to the brick, is that how you should do it or should you just build the program?

P.S
When I run the color sensor example in the brick it confuses orange and red which is problematic to me because I need to create a rubik’s cube solver and it has to distinguish between the colors, is there any way to solve this?

Thank you,

EDIT1:
I am using a 8gb SD card with the 4gb image booted to it and the dll all from the site,
http://www.monobrick.dk/guides/firmware-guides/monobrickfirmwaresdcardwindows/ – the 4gb image

http://www.monobrick.dk/guides/firmware-guides/running-and-manually-transfering-a-program/ – the dll

I downloaded both of them on 4/9/14 (telling this just to make sure that there were no updates or mismatch between the versions at that date)
