How to Enroll a new Users to a BioLite Net Terminal using C#?

I have made this method based of the examples provided by Suprema. When i execute this code it gives me the error "Cannot enroll the user" and the returns error code -105.

The handle = 1, deviceType = 2, _TemplateData = null and TEMPLATE_SIZE = 384 the are all variable asigned ate top of the script.

int handle = Recursos.handle;

//BS_RET_CODE BS_EnrollUserBEPlus( int handle, BEUserHdr* hdr, unsigned char* templateData )
if (txtInicioData.Value.Year < 2020)
{
    MessageBox.Show("Data de inicio não deve ser inferior a 2020.");
    return;
}
if (txtInicioData.Value.Year > 2020)
{
    MessageBox.Show("Data de inicio não deve ser inferior a 2030.");
    return;
}
//
if (txtDataFim.Value.Year < 2020)
{
    MessageBox.Show("Data de Caducidade não deve ser inferior a 2030.");
    return;
}
if (txtDataFim.Value.Year > 2030)
{
    MessageBox.Show("Data de Caducidade não deve ser superior a 2030.");
    return;
}
//

I'am using the BS_EnrollMultipleUserBEPlus function and this is my UI User Interface
