Need help adding exceptions

Hello all

I have been using Comodo services for a long time and I have used security software for as long as I remember.
However,one thing I dont(out of many) is how to add exceptions to the CIS.
basically I am playing a game which comes with GameGuard and other players are saying to add Gameguard.des, Gamemon.des, Aion.bin, nclauncher.exe to trustworthy applications
And as I said above,I dont know how to do that.
Could someone please guide me?

Thanks
