I am not sure ED is directly download-able from GOG, but maybe you can help.

I started playing Eternal Damnation, but I got stuck: I am nearly the begin I just left the asylum and reached the girlfriend house. She mentioned I should go to her workplace, where is it? I find nothing! The city seems clean of hostiles, but I cannot see where I should go.

Thanks for help.

After you have seen her, you should then leave the building and go down the stairs and follow the pretty liner path until a cut scene plays of you jumping out of a window, and it should then load the next map of you waking up in a hospital.
