Hello Stoney, (cool nickname)
This is a Joomla problem. Your hosts php.ini has been set to have "fopen_wrappers" to be OFF, where Joomla! needs it to be "on" to install software using the "install from URL" functionality.
There are 2 solutions:
Have your isp to turn allow_url_fopen = On
OR you can use an alternate installation method:
1) download the extension to your harddrive by clicking this link:
http://network.intellispire.com/public/com_updater.tgz
2) Login to Joomla, click "Install / Uninstall" then use the "Upload Package" functionality.
Once it is installed, the system will work IF you have EITHER "curl" or url_fopen on your server. If you have neither, then unfortunately the installer can't work.
(Most people with allow_url_fopen = Off DO have curl installed)
