Open with notepad, the Config.xml in the install folder (likely C:\Program Files (x86)\HCC2
It should read:
Code:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<config>
<config-desc>Update information</config-desc>
<servers>
<server nick="HCC Update Server">http://www.istaria.info/updater</server>
<!-- <server nick="Offical Update Server (hcc.reclamation.dk)">http://hcc.reclamation.dk/updater</server> -->
</servers>
<update_check>http://www.istaria.info/update_check/</update_check>
</config>
If you don't see anything with www.istaria.info inside then you'll need to grab the file again
