Please check if your method "Certificado" loads a certificate correctly.
I attached the sample application that works ok with the latest SecureBlackbox version (Rename the attached file to zip).

It works succesfully!. The method "Certificado" is loading correctly the certificate but the error was that it looks for a certificate in a wrong store for cert3. I was looking for certificate in store.SystemStores.Text = "ROOT" instead of store.SystemStores.Text = "CA"

I am reviewing the example at: http://www.eldos.com/security/articles/4583.php in order to generate CertificateValues and RevocationValues.

I don't understand how to obtain BufPKI from TElOCSPResponse object.

It is a mistake in the article, it should be OCSPResponseBuf.

Is the same to set PKIData.Data to OCSPResponseBuf or set to OCSPResponse.Certificates.Certificates(0).CertificateBinary?

I answer myself, the size from both are not equal. Is ther any other form of knowing the response size without having to save it to a buffer?

If not, we need to do this:
Dim OCSPResponseBuf As Byte()

'request to OCSP server
OCSPResponse = OCSPRequest()

'save without buffer in order to know the size
OCSPResponse.Save(Nothing, 0, Size)

'set the size of buffer
SBUtils.Unit.SetLength(OCSPResponseBuf, Size)

'save to buffer with the correct size
OCSPResponse.Save(OCSPResponseBuf, 0, Size)

Unfortunately, no. This is the only way at the moment
