Probably that's firewall of yours.Turn it off & try again. I'm using NIS2004 from Symantec & got the same problem.Downloading from some sites does not starts up while my firewall is "on".It blocks only starting so I just turn it off, start my download & turn firewall on.
Thanks, Red Knight!
That was it! I use ZoneAlarm v6.5.731. I would never have guessed, thought it was a corrupt NET framework installation or sth.
Thanks so much!
