I'm trying to install 1.5.2 on my pc with XP and it's having troubles downloading the required files. During the File Download Phase, it hangs trying the get updallocator.php. Something about unable to resolve www.safer-networking.org. I know I can get to this url via the browser but during install, it doesn't work.

I installed this on another pc on the same network and it worked fine...

Any assistance appreciated...
