DIDISOFT - OPEN PGP Null pointer exception on decrypt

Question

I am using OpenPGP from didisoft to encrypt and decrypt files. I have an encrypted file and the private key corresponding to the encryption key. But when I try to use the DecryptFile () method, I get a null pointer exception.. I cannot figure out what the problem is. Any help would be appreciated. Code:

public void decryptFile(string filename, string destPath)

string password = "xxx";
                string encFile = System.IO.Path.GetTempPath() + filename;
                string keyFile = ConfigurationManager.AppSettings["DecryptKeyFile"].ToString();
                PGPLib pgpDecrypter = new PGPLib();
                File.Create(destPath + filename);
                string a = pgpDecrypter.DecryptFile(encFile, keyFile, password, destPath+filename);  // I get the error on this line
