The qualified electronic signature is invalid - What does this mean?
When opening our PDF invoice with a qualified electronic signature in Adobe Reader, you may see a message stating that the validity of the signature is unknown. In this case, please manually add Digital River as a trusted issuer of this signature.
Depending on your Adobe Reader version, look for these settings under 'Signature Properties', 'Trust' or a similar term.

Please be advised that while Adobe Reader is able to display our PDF documents, it is not suitable for confirming the validity of documents with qualified electronic signatures. For this purpose, please use software like the free digiSeal reader.
