I had a major hard drive crash and reinstalled Acrobat 6.0 professional and restored my certificates and keys from backup (I thought).

Every time I try to sign a doent I get a "Certificate Security Alert. Creation of this signature could not be completed. Unexpected internal program error (CMS Handler Line 79)" When I check the certificate, it says it has a private key associated with it.

I would be eternally grateful for any assistance.
