Invalid signature

I got some problem with the signature on an A record. Could not reproduce this one, since each signature is unique in time. But I have attached the original file and the signed file.

Auditor started
Auditor starting on mynta.org
6: SOA differs : from 2009021403 to 1258980788
6: Auditing mynta.org zone : NSEC3 SIGNED
3: RRSet (www.mynta.org, A) failed verification : Signature failed to cryptographically verify, tag = 56978
6: Finished auditing mynta.org zone
Auditor found errors - check log for details

It is either the Signer who produces the wrong signature for the www.mynta.org or the auditor who performs a faulty verification.
