help?

I’m new to cubase and recently purchased a Yamaha AG03 Mixing Console Interface, I’ve been trying to record vocals and a piano track into cubase but nothing ever records into it. Every time I open a new project it comes up with;
microphone (high definition 1) ---- in–unmapped
microphone (high definition 2) ---- in–unmapped

I have a 1 microphone set up into my interface which i can hear through my headphones, I’ve watched the tutorials and nothing has helped. I’m starting to get quite upset and extremely frustrated as I’ve spent a lot of money and saved for a long period of time. Any help would be greatly appreciated.

Have you done the setup as described here:
