Developers, can you please check the ...\blender-2.58a-windows32\2.58\scripts\startup\bl_ui\space_userpref.py at line 884 "user_addon_paths.append(os.path.join(user_script_path(), "addons"))" I got this error --> str is not callable I think it should be "user_script_path" instead of "user_script_path()" Thanks, Paolo
