Error 8921,254

Yesterday on 10-06-12, a technician came to my house and changed my modem because of an upgrade to my satellite internet. Everything seemed fine until a few hours later I noticed that I had not received any live updates for several hours. I tried to manually update but received error 8921,254 unable to connect to server. I tried the steps the web support page suggested but no success. The funny thing is I have good internet connection, my son's computer which has NIS 2012 installed is updating fine and we both are connected to the same wireless router. I have checked on the forums and can find only two instances of this error. I used the flush dns suggestion, powering down my modem and router. I even downloaded the intelligent updater and installed the latest definitions from 10-06-12 on my computer with my internet connection. I ran live update, rebooted after that and still receive the same error. I would appreciate any suggestions. Thanks
