I have a problem with Ecodesigner for AC 13. When i open the option "Facade Shadings", the AC shows anything in the window (look at the added image), also i didn't have a option for Activity, that shows "Missing".
I saw here in forun a similar problem (http://archicad-talk.graphisoft.com/viewtopic.php?t=33306&highlight=ecodesigner) but i didn't obtain the solution.
to find out what kind of ED license is stored on your key. You should see something like the screenshot below for my license, showing that I have a USA version.
I would guess that yours says INT, but perhaps there is a POR or BRA version. If you see POR, e.g., try copying the folder and naming the copy POR. You will have to restart ArchiCAD to find out if it makes a difference.
