Wiki Plugin (wiki pages not displaying)

Wiki pages are not displaying. When I attempt to view, the result is "Page not found."

System/Set up:
- This is a 100% fresh Wordpress installation (WP version 3.5.1).
- Only installed and activated plug ins are WPMU DEV Dashboard, Jetpack by and Wiki
- Theme installed is default theme Twenty Twelve
- I haven't made any other modifications yet

Order of Events:
- Installed wordpress
- Installed WPMU DEV Dashboard

- Status of test wikis is public and published

Clicking on the "view wiki" link results in "Page not found"

Your installation and usage instructions don't indicate that anything else is required to make this function. Please advise.
