I had no idea how else to word the title. I'll try my best to explain what I need help with. Don't laugh at my newbieness, please. -_- I don't even know if theres a solution to my problem. Bear with me, please?

So yeah, most of you are gonna think I'm a desperate idiot, but I need some sheet music, and there is only one place where I don't actually have to pay for it, instead i need a login id and password.
I'm pretty vague when it comes to explaining so this is what I mean: http://www.herndonorch.org/hmmusic4.htm

When I click any of the links for the music sheets, I get that little popup that asks for my login and password. Which I have no access to, because that info only belongs to students of some school thousands of miles away.

So my question is, is there any crack or something that'll get rid of that screen?

thanks for any help..even if its a no.
