What am I doing wrong?

You have no power supply, and the op amp output is shorted to the positive power supply pin.
When you get these two items fixed, note that, since the input is referenced to zero volts, you will need positive and negative power supplies.

This is the error I get:

Why not to start afresh and see what comes out?

It will take less than 5 minutes.
I started fresh, fixed a few things, and then got this new error:

Is V1 a VAC or VSRC source? The syntax for an AC sweep is different or each type. See Chapter 10 in the User Guide.
I would advise you not to try the noise analysis until AFTER you get the AC analysis running. Debug one error at a time.
