My first problem with this site

[NiteFox]

Code:

E:\Diablo>ping d2mods.xfernet.com

Pinging d2mods.xfernet.com [216.234.186.144] with 32 bytes of data:

In other words, the site itself is down. Snuffed it. Ceased to be. Whether this is a temporary thing or not has yet to be seen.

Until then, Google is your friend. I'm sure there's bound to be a mirror out there for the mod you seek.
