Hostname gone?

Hi,

since yesterday, my free hostname (on the kicks-ass.org domain) does not work anymore. I use a fritz.box to keep it up to date, which shows "Account temporarily disabled" since yesterday. I couldn't see why my account (which worked fine for a few years that way) would cause any problems, so I assumed it was a problem on DynDNS, but as it's still not working I'm started to wonder whats wrong and logged into my account which does not show the hostname anymore.

I didn't get an expiration-warning-mail or something. Só what could be wrong?

Greetings, theromi
