Vog, verbatim from S&D help follows - it was also on their forum site. In my case the list of download mirrors was blank - guess what it now has S&D Europe and USA!
"The integrated update is not working. Are there any solutions for this? FAQ #010" "The main reason for this problem is that you need to use a proxy server to access the internet. In that case, the proxy server is already set up in your browser, where you can look up it's settings and enter them into Spybot-S&D.
In Mozilla, you can find the Proxy settings if you open the Edit menu, choose Settings... at the bottom, and navigate to the section Advanced - Proxies. In Internet Explorer, see the Menu Extras - Internet options, go to the tab Connections and click the Settings button at the bottom.
Back inside Spybot-S&D you need to go to the settings page, and scroll down to the entry Automation - Web update - Use proxy. Now check the box below it, and a dialog will appear where you can enter your proxy settings. The format is host:port (the host is the name, the port the number you found in your browser). If you need to access your proxy using a login, you can use the format username:[email protected]:port"
I have just installed 1.3 and set the proxy as instructed by S&D. I tried an update but got an immediate message that no later updates were available even though there was no connection to the server. No connection ever materialised. Having read these posts just previously I decided to untick the "Use proxy" box. It then worked immediately and I got the update: a very exciting "English help for Tea Time". Well, I was wondering what TT was.
