I think the get_postalcode error a red herring.

Try the following:

[TiVo [p0] ~]# get_postalcode

You should get the response 02000 (for NSW)

If you don't, please do the following

[TiVo [p0] ~]# cat /etc/postcodezones

And show what results you get.

If you did get 02000 then it's your ISP's proxy still causing issues. Try the following:

Enter the following commands (in red) at the putty prompt:

[TiVo [p0] ~0]# echo " " >> /var/hack/etc/emuProxyZA.conf
[TiVo [p0] ~0]# echo "proxyIP=proxy2.tpgi.com.au" >> /var/hack/etc/emuProxyZA.conf
[TiVo [p0] ~0]# echo "proxyPort=3128" >> /var/hack/etc/emuProxyZA.conf
[TiVo [p0] ~0]# reboot

Once your tivo is rebooting, you can close putty.

Once restarted force a daily call using TiVoWeb or TiVoWebPlus.
