Hi -
"Floating nodes" means that there are nodes with no DC reference to ground, or no connection. You need to add some reference - like a 1000 megohm resistor - to placate the simulator. Or, the subcircuit names aren't matched up with the symbol names so they are unconnected.
This might also be helpful (especially with undefined subcircuits, I always have issues with associating the models and pins correctly) if you haven't looked at it:

Just a question on measures with Orcad.
I have to test the frequency response of a preampli circuit.
I have set AC VIN 1V and I have create a new simulation profile with AC Speep from 0.01Hz to 1Meg.
It's correct?
How can i measure the THD distortion?
I know that I create a Transient simulation centered to 1khz.
