Working a few minutes ago at least, both the Manual 1.1 and the Windows download link of Classic Machines Vol.2 (Vol.1 expired July 1st!) and the update to Spark 1.1.2 also worked for me.
EDIT: oops, you're right, Classic Machines Vol.2 didn't download... the file I got was just the usual HTML with the error.
btw, this 1.1.2 update solves a lot of tiny little issues and improves the feature set greatly, so... I'm quite glad with it
