I've just gone through to get the latest versions of these sets for the auto-downloadable; and two major issues with the way you're doing this thread:
1. If you post an update, edit the original post - either to add the update there, or to remove the attachment. Or at LEAST to say that it's an old version.
2. The sample levels - or at least the huge OGG tracks for them - should be a seperate download.
