might be cos there's too many people trying to access it at once - it's sadly just run from an xp server in my house (i keep meaning to upgrade to proper hosting, but keep not getting round to it). you could alternatively try http://abandon-hope.dyndns.org/math/files/index.htm as that links straight to it without the dot.tk re-router...

i am listening to your band now on myspace, i like it! the drumming in particular is outstanding (i used to be a drummer so i always appreciate good skinwork ) can't believe it wasn't recorded in a studio! good work!
