I'm glad the tutorial showed up. If the tutorial version is 1.0.006, that is the current version. If Tutorial 12 in the tutorial pane does not show up try these steps:
1) click in the tutorial pane and refresh the page
2) restart the entire browser
3) try a different browser
4) clear the browsing history and cache
Particularly on Chrome, we find that you have to sometimes clear the browsing history and cache in order for the new material to show up. That's probably why moving to a new machine helped solve the problem, as you had a new browser.
