Wiki Plugin (wiki pages not displaying)

Problem:
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 WordPress.com 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
- Installed Wiki Plugin using your Dashboard
- Made some wiki categories
- Added a couple of test wikis
- Status of test wikis is public and published

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