We went back to the original user and moved to trash the folder <home folder>Library/Caches. From there we went and moved to the desktop <user>/Library/Preferences/com.apple.TimeMachine.plist.
We then restarted the mac. Upon restart, we entered Time Machine and it worked fine. The timeline had reappeared!
Apparently there was something in the Cache that was causing the problem.
Time Machine has had a few issues. The biggest one seems to be this.
In order to remove US input source, for the adventurous few (see warning in previous reply), here are the procedures:
1) Make a backup of your preferences, via Time Machine or otherwise.
2) Download a plist editor.
3) Uncheck ALL input sources in System Preferences > Languages & Text > Input sources EXCEPT for 2, the one you want as primary, and the one you cannot remove. You can add them back later, just disable them for now.
3) Open ~/Library/Preferences/ByHost/com.apple.HIToolbox..plist * is a HEX string (hopefully) unique to your machine host using your plist editor.
4) Under “AppleEnabledInputSources”, delete the first node… should be something like:
<dict>
<key>InputSourceKind</key>
<string>Keyboard Layout</string>
KeyboardLayout ID
<integer>0</integer>
KeyboardLayout Name
<string>U.S.</string>
</dict>
5) Save, Login and out of your user, and you’re done.
If you don’t feel like using Terminal, here’s an even easier solution:
Go to System Preferences
Click on Accounts
Click on Login Options (house)
Click the lock to makes changes
Put in your password
Check “Show input menu in login window”
