For some reason when I try running the app-it's telling me that it can't run due to, "UNKNOWN PUBLISHER." Has anyone else had any problems with this? Or know any ways that I can fix it? I've checked my computer for updates, doing a system check, deleting and reinstalling, merging all files into one. Yet, nothing seems to work. Which really sucks, because I've seen good things about this game and I really wanted to play it.
