OK… IMO, you should keep the UFX1204 USB ASIO x64 driver as the one used by Cubase and deactivate the ASIO guard, at least, for now. This done, I’m going to ask you also a screenshor of your Studio>Audio Connections>Inputs pane (to check what audio busses you have already defined) and an added one for your Studio>Studio Setup>MIDI port Setup pane (to see what MIDI port(s) is/are available).
After this, few questions…
- What have you tried to record, audio or MIDI sources (if the latter case, with an instrument track or VST rack instrument, which involves a pure MIDI one ?)
- In any case, What have you as selected in your Input Routing area (either in the inspector or in the Routing rack of the MixConsole) ?
- A last question before going further : when starting a record (with the Record Enable button activated) do you get either a MIDI part or an audio event as a result, and do you hear what you are recording ?
Enough for now, I think… 
EDIT - Just looked more closely at the UFX1204 : it’s an USB mixer with no MIDI connections, so, unless you have a separate MIDI interface unit that allows you to record MIDI data, dismiss all what I stated related to MIDI…
