stumped - dynamic DNS stopped working - ddclient and www.zoneedit.com

I've been running dynamic DNS updates perfectly for a year with ddclient and zoneedit.com.  Last week, it just stopped updating - no changes on our server.

The config /etc/ddclient.conf:

daemon=300                              # check every 300 seconds
syslog=yes                              # log update msgs to syslog
mail=x@y.com                     # mail all msgs to root
pid=/var/run/ddclient.pid       # record PID in file.
# Another d-link nightmare, just get the IP from the web.
use=web, web=checkip.dyndns.org/, web-skip='Current IP Address: '
##
## ZoneEdit (zoneedit.com)
##
server=www.zoneedit.com
protocol=zoneedit1
login=<user>
password='<pwd>'
<name>.com,www.<name>.com,beta.<name>.com


...running the command:

sudo ddclient -force -file /etc/ddclient.conf ; echo $?

yields:

0

I get an email stating that the ip was forced but nothing changes at zoneedit.com.

WARNING:  forcing update of www.<name>.com from 12..34.56.85 to 12.34.56.17; 15 days since last update on Thu May 29 11:36:53 2008.

Stumped.  Any suggestions?
