Where is DIRECTORY_ENTRY_LOAD_CONFIG? In the changelog (https://code.google.com/p/pefile/) one can read:
"Version: 1.2.10-60 Besides some small bugfixes in this release I've added functionality to parse the LOAD_CONFIG data directory. Now one can access this structure's fields like, for instance, pe.DIRECTORY_ENTRY_LOAD_CONFIG.struct.SecurityCookie or pe.DIRECTORY_ENTRY_LOAD_CONFIG.struct.SEHandlerTable" -- https://mail.python.org/mailman/listinfo/python-list
