No longer updates dd-wrt

DD-WRT on a Linksys WRT54GL. Was working fine for a few months then started getting the following error

Current IP Address: xxx.xxx.xxx.xxx

Thu Jan 26 16:26:02 2012: I:INADYN: IP address for alias '[mysite].dyndns.org' needs update to 'xxx.xxx.xxx.xxx'

I updated the username and password in the system to ensure that they were correct, still getting the same error. In my host list, they do not appear as blocked. I have a paid DYN account so id assume i wasnt hitting the free update threshholds.
