using System;<br />
using Perpetual_Settings;<br />
namespace Brazen_Mail<br />
{<br />
	/// <summary><br />

		static Setting()<br />
		{<br />
			test = new PerpetualSettings();<br />
		}<br />
	}<br />
}<br />

But when running the code I get this error.

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll
