DNSSEC: signature expired

Hi!

I have two domains. One of them I set the dnssec in registrar and everything worked fine. The other domain, when I try to set the dnssec, my registrar gives me a error: signature expired. I already try to run tools/dns_update but out of luck, I still get signature expired from my registrar. I already read this topic here but it did not help.
Any suggestion?
