I found there is a simple way to disable the DBFZ anti-cheat which allows the toolkit to fully work with DBFZ. 

Instructions to disable anti-cheat.

You should always only use the toolkit in offline modes in game. But especially make sure you select offline mode when launching this anti-cheat disabled version of DBFZ. We take no responsibility for you getting yourself banned if you use the Lab Monster Toolkit in online modes.
