Do you have a sheet chosen for your game? You can drag any monster from the Compendium Tab onto the tabletop and it will add a sheet for that monster to your current game. You will need to provide artwork for it, and if there are multiple copies (i.e. a party of goblins), you will need to set them up as mooks. [Token linking instructions.] Once you have set it up, you can drag new copies from your journal tab whenever you need them. (Note, drag from the name, not the three lines to the left. They are used for changing order, not pulling onto the table) Have you taken the Tutorial ? A lot of this is explained there.
