errors when using with D6 are critical:

warning: Invalid argument supplied for foreach() in C:\vhosts\buildplane\public_html\includes\menu.inc on line 258.
warning: array_merge(): Argument #1 is not an array in C:\vhosts\buildplane\public_html\includes\menu.inc on line 323.
warning: Missing argument 1 for drupal_get_form() in C:\vhosts\buildplane\public_html\includes\form.inc on line 69.
warning: call_user_func_array(): First argument is expected to be a valid callback, '' was given in C:\vhosts\buildplane\public_html\includes\form.inc on line 371.

This prevents module from working properly. I have both tried the 'patch' to the D5 and also downloaded the integrated version for D6, but both produce the same bugs. Is there a known fix. Is it perhaps somehting to do with the $path and $arg which appear undefined?
