That's a real shame. Bear in mind this is circumstantial, but I had enough orders turned around or held in limbo when I ran a store to suspect, strongly, that the book's dropped out of print and their website hasn't caught it. If you can, I'd get the funds back and order it elsewhere.
Failing that, check their forums and ask the admins there, odds are they'll have some email addresses for real people. Failing that, I'd try and dig up email addresses for the editors of some of their titles (Or the guy who writes Hack/Slash come to think about it). Should be listed in the books. Failing THAT, PM me, and I'll see if I can dig up something else for you.
