Error with HSM in FIPS mode


We are using ncryptoki to sign PDFs with our Safenet HSM. I have attached the code (VB) below.

Everything worked fine the last years. But now the CA required us to activate FIPS mode on the HSM for the new certificate. Now we get the error -2147483542 at

        pdfSigner.SignPDFFile(infile, selector, outfile)

As said, the only thing that has changed is that the HSM is now in FIPS mode. Do you have any idea of how we have to adapt our code so that it will work again?

Thank you very much
