Importing pyplot crashes python

Hi,

  I decided to upgrade to matoplotlib 0.99.1. I'm on Windows XP. I downloaded matplotlib-0.99.1.win32-py2.5.exe and ran it. It seemed to install. Now when I try "from matplotlib import pyplot", Python crashes with one of those "pythonw has encountered a problem and needs to close" messages. I tried uninstalling matplotlib, and I also uninstalled SciPy and upgraded that to the latest version (0.7.1) and then reinstalled matplotlib. Still crashes. Importing numpy on its own works, as does importing matplotlib on its own.

  How can I fix this problem?

Thanks,

···

What does the command `python.exe -v -c "from matplotlib import pylab"`
say?

MPL 0.99.1 contains a bug (#2903460) that crashes the _path module on
slow Pentium CPUs (at least when using Python 2.6). A updated installer
is available at <http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib>.

It might help to add the path where python.exe is installed to the
Windows search path. E.g. try `SET PATH=C:\Python25;%PATH%` before
running your program.

  I forgot to mention that I'm using Python 2.5.2. Has anyone else encountered this problem?

Best wishes,
