When you were in this box you have to enter more info.
You can check "show all asteroids" --make sure you reduce the FOV to a degree or
less as you will overload the system.

Or you can enter a the number of asteroids in the "show first" box that will get to
the magnitude level that will show your particular asteroid.
I normally select 20,000 unless it is a faint fast moving or obscure asteroid.

Place the mcporb.dat file directly into the Guide9 folder.
