How do I import a Netlist ?

[BeauWebber]

Hi,
I have a schematic for a partly built design created by a colleague (using DipTrace), and I want to try and complete the design in Proteus.
DipTrace can export the Netlist in a range of formats.
I see in the Forum : "You can then start ARES and import a netlist (if allowed by the version you are using)."
But how do I do that ? - I have searched the menus, help and the Forum, and am still none the wiser.
I have Proteus 8.7 Design Level 1.
cheers,
Beau
