system.typeinitializationexception' occurred in mscorlib.dll Visual Studio 2015 C#

Question

So I cannot find a solution to this problem: I am using a .DLL Library which I need to interact with an external device, but when I'm using the .DLL (bold line in code example) I get the error: system.typeinitializationexception' occurred in mscorlib.dll

The .DLL should be correctly implemented through properties in the solution explorer of Visual Studio 2015 and the code works with no problem on 2 different laptops, but this error occurs when I try to use it on my desktop - where I need it to be functional.

Code example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Net;
using System.Net.Sockets;
using System.Text;
using Inomed;
using Inomed.Software.CommonLib.NeurostimInterface;

namespace Server3
{
    static class Program
    {
        **public static Neurostim_interface myNeuro = new Neurostim_interface();**


        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}
