Re: ERROR - "Incorrect padding" in listclusters command (github version)

Hi Justin,

No need to apologize!
I could understand how busy you were as I myself started classes this week
here in the UK.

Per your instruction, I will try it again and report back, if needed.

Many thanks for your detailed response,
Joseph

P.S.
How can I know the version number?
I just did 'git pull', installed it ('sudo python setup.py install'), and
typed 'starcluster --version'.
The version number returned, however, is '0.9999', exactly the same as
before.
