Certificate problem downloading patches

Today I am having problems downloading patches on Solaris 9 & 10.The log in part shows :

2006-10-25 09:55:27 Wed Oct 25 09:55:27 GMT+00:00 2006(ERROR) => com.sun.patchpr

o.security.SignatureValidationUtil@c2ee15 <=SignatureValidationUtil.validateJarF

ile(): The specific Jar file is not signed by a known digital certificate. 12421

5-01/.diPatch CN=Enterprise Services Patch Management, O=Sun Microsystems Inc

And the response to smpatch download is:

124215-01Unexpected errorwhile accessing the requested patch.

Any suggestions?

John.
