Interface.getConnectedLaunchpads Doesn't work !

[vukast]

Here is my code (Program.cs) :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Midi;

using LaunchpadNET;

namespace LaunchPad
{
class Program
{
static void Main(string[] args)
{
Interface lint = new Interface();

        lint.connect(Interface.getConnectedLaunchpads()[0]); //Connects with your Launchpad
        lint.setLED(5, 5, 127); //Sets the LED at position X=5;Y=5 to orange.
        Console.Write("Test");
        Console.ReadKey();

    }
}

}

It seems to occur from the OutputDevice.Open method, bizarely the error getting thrown from within the Midi.OutputDevice.CheckReturnCode method.

EDIT: This only happens when connecting to the launchpad on start of the application, if there's some delay i.e. due to waiting for a launchpad to be connected or w/e, it's fine.
