Don't know what to tell you.
If you're still having problems and wanna PM me with an e-mail address I'll be happy to send it to you.
must confirm that link is broken for me as well
That's bizarre - I just tried it again and it downloaded just fine.
I'll PM you the link I have that should work for you.
Is there anything you can post about whatever error message you get or whatever happens when you try the "Useful Materials" page link, so maybe the devs could check on it?
