When I submit the 3b8 update, I forgot to update the download link, so the 3b8 download link was originally wrong. It linked to a pre-3b8 alpha release, and should *not* be used. I think there's about 10 people who downloaded that.

Then, when I updated the download link, I provided a sourceforge file listing, but versiontracker automatically grabbed the first link on that listing, which is only the application, not the full scenario. Looks like another 10 people may have grabbed that. Hopefully the correct download link will be updated soon, but for now, here is a link to SourceForge which has all of the EMR 3b8 download links.
