I tried to go to the LoreSoft site (http://www.loresoft.com/) to get NetSpell and ran into this DNS lookup error.  It's been like this for a couple of days.

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /Default.aspx.

Reason: DNS lookup failure for: webdav.loresoft.com

Is NetSpell still supported?
