Cannot download Timing libraries (eg MsTimer2, Metro).

I am attempting to download the MsTimer2 and Metro timing libraries, but after clicking the links the pages just time out and are not available. Other libraries are okay. I have tried using IE, Firefox, Chrome - is there a problem I am not aware of? Thank you.
