Case Number 0218019035: I can not use my identrust electronic signature/certificate with Acrobat 9; it worked fine until three weeks ago. i have gotten an error message for the past three weeks. Identrust has verified and replaced my certificate and has indicated I now have to contact Adobe. Acrobat still rejects my replacement certificate with an error message "Windows Cryptographic service reported an error: the data is invalid. Error code 13” What can be done. Do I need to remove and reinstall Acrobat 9?
