LoadLicenseKeyData dosn't work correctly

I just bought a license for my library and am having issues loading the license file. It always comes back as false. I know that i am getting the license information and passing it in but i am always getting false back. I have used both the LoadLicenseKeyData and LoadLicenseKeyFile both return the same infomation.

Code used for LoadLicenseKeyData

sfFTPLib.Interop.Global global = new Global();

			string text = File.ReadAllText(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "Resources\\SmartFTPLicenseKey.txt"));

			if (global.LoadLicenseKeyData(text))

			{

				MessageBox.Show("Loaded License File");

			}

			else

			{

				MessageBox.Show("Failed to load license file");

			}

Code used for LoadLicenseKeyFile

sfFTPLib.Interop.Global global = new Global();



if (global.LoadLicenseKeyFile(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "Resources\\SmartFTPLicenseKey.txt")))

			{

				MessageBox.Show("Loaded License File");

			}

			else

			{

				MessageBox.Show("Failed to load license file");

			}

Any suggestions on how i can fix this issue? I am using Win 2003, IE 7

The customer has bought a license key for the FTP clients instead for the FTP Library.
