This problem pre-dates the switch to new forum software and is therefore unrelated. On an older desktop running XP, I can’t get to Qt3 forum.
I can access qt3 (as I am now) using the same DSL signal on my Win7 laptop. This problem occurs using Firefox 18.0.2.
–I did the ipconfig /flushdns suggestion, but it made no difference.
–I tried turning off the firewall, same result.
–I tried using Google Chrome, same result.
–I tried disabling the anti-virus (McAfee VirusScan Enterprise 8.5.0i), same result.
My only idea is the try another browser. Download chrome and see if that can view QT3. Maybe you just have an ancient version of IE that the new software doesn’t recognize.
