The Google App Engine unexpectedly stops working, with the error "you probably are not getting the Python PIL module",

For more than a year now I have been developing applications on GAE (with Windows / Python), and although I am not an expert, I have always managed to run applications!

The application I'm working on now works great on the local host at lunchtime today. Without any changes, I came to it tonight, and the application will not start in the App Engine launch bar, a warning triangle appears when I try to do the following in the log:

INFO     2013-12-03 23:46:06,766 devappserver2.py:557] Skipping SDK update check.
WARNING  2013-12-03 23:46:06,776 api_server.py:317] Could not initialize images API; you are likely missing the Python "PIL" module.

I tried to launch the Hello, World application, since I know that it worked fine before, as well as several other applications that I developed that all worked fine, and they all produce the same error.
