This is with League of Maidens 1.7.0.a. After clicking on "Start" in Steam, a window appears titled, "Update required", with the text, "This patch requires an update to your LOM game data files. Do not close to avoid data corruption. This process may take a few minutes." Below that is a "Confirm" button. The "Confirm" button does not respond to mouse clicks. I've waited 20 minutes to see if it recovers, and it doesn't.
