I'm working with Windows XP SP2 and Norton Internet Security.
So I just deactivate the Internet Security, to shut down the firewall and don't care about tunnels and IP's.
and no, I didn't play with the internals g.
If you asked me, I would say, I'm just doing some stupid thing wrong, when I try to fix the help-database.
But don't you know a direct way, to start it, so that I can be sure, the database isn't the problem?
