FlyingFman: It doesn't work all the time for me, although that may be due to GOG Galaxy's incessant connection problems. Even right now, the client won't connect to GOG, but the game still works. Go figure.
EDIT: The client finally connected, and the menu is gone again. Oh, and now it's here. The issue is really intermittent.
Hmm, I opened the game up this morning to see and it worked, but if it's intermittent that's gonna be annoying. Try running the game without the client. It didn't work before the patch, but maybe it will now?
