Init RSACryptoserviceprovider and RSAParameters from files

Hi,

I'm trying to initialize RSACryptoServiceProvider/RSAParameters with private and public keys that I'm getting from a third party (in file). Environment is Windows Mobile 6.1 and .Net CF 3.5.

I was expecting that the following code will work, but I'm always getting a " 80007001" error on the Importparameters call. I have read many posts and many comments, but for the moment I'm still stuck with this issue !!

Any help and advice will be welcome. Thks !

Here is the code :

    private void button1_Click(object sender, EventArgs e)
    {
        RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
        RSAParameters RSAparams = new RSAParameters();
        RSAparams.Modulus = new Byte[]{
