"ValueError: 'Time Period' is not in list" in Notebook. Why?

Hi Q,

As I run the notebook today I got error message as follow:
...

/usr/local/lib/python2.7/dist-packages/pandas/io/parsers.pyc in _set(x)
1287
1288 if not com.is_integer(x):
-> 1289 x = names.index(x)
1290
1291 self._reader.set_noconvert(x)

ValueError: 'Time Period' is not in list

...

Why? Something is changed?

Strangely as I run it today, the error is gone.
