I recommend filing a complaint with your atty general office, BBB, your registrar of contractors. Hurd will pay dearly if they don't fix your windows because they were successfully sued before.

I'm guessing they would be up for another class action since they were sucessful before and looks like Hurd has continued selling these windows with same problem.
