I cannot download Scratch 1.4 from the following page.
http://scratch.mit.edu/scratch_1.4/
It seems the download site is down.
http://download.scratch.mit.edu/
Many scratchers reported me about the same trouble.
Thank you for your help.

Same here.

My browser / operating system: Windows 7, Firefox 26.0, Flash 11.9 (release 900)

I confirm the download site is back.
Thank you!
