Spectrum Analyzer Master Bus

I’m trying to use Roger Nichols Inspector XL on the mater bus in Cubase SX 2.0. I have it placed as an insert effect on Bus 1 but it’s not responding when I tweak the EQ. Can anyone help with setting this up properly. Thanks in advance

You need to put it on one of the last two inserts to be post fader.

Thank you!! Works perfect now.
