Get the v5.5.7 patch here:
It corrects the cybug/map directory ini file setting that was added but buggy in v5.5.6.
It updates the 3D engine to v1.0.6 giving you some more eye candy with a cool end game sequence for the highest scoring Cybug thats still alive.
Non english language system owners can now use the 'SaveAs=Low' setting in the 'aiw_config.ini' file to use v1 encryption to prevent system lockups when running battles. See the encryption FAQ in the tutorials page for details.
Other minor changes were made to the Cybug editor interface.
