While I'm not sure how to edit the config.cfg file, I do know that you need a console to make sure that the commands are being input correctly. You CAN inject pubconsole and load up fine, you just can't enter any codes into it because it will crash afterwards.
You have to use a console in order to activate Nico's dll. So just inject pub console and nico's dll and you should be ok.
However if you want another alternative, DanK just put out a new console recently as well, a link here:
