What is the actual command line you are using?
Note that the last trunk known to complete translation correctly was 
around July 3, version 20258fbf10d0. You can see the pypy buildbot 
history at http://buildbot.pypy.org/nightly/trunk 
<http://buildbot.pypy.org/nightly/trunk/> The "tip" version does not 
translate, someone should fix it soonish.

To translate on windows, you must use pypy (only 32 bit is available)  
or 32 bit cpython and follow the directions here 
http://pypy.readthedocs.org/en/latest/windows.html?highlight=windows
especially this bit: editbin /largeaddressaware <translating python>
