Soundtrack link fixed!

Hello, folks!

Many months ago, user spacecxse left a comment saying that the soundtrack was no longer accessible. I'm very sorry for taking this long to fix this! Now that I have access to my computer again, I've updated the link, tested it, re-uploaded the new PDF, and tested it again. Looks good to go.

Much thanks again to spacecxse for catching this. Moondog did a fantastic job with the soundtrack, and it is vital to gameplay, so I regret that it's been inaccessible for so long.
