I'm anticipating a future minor bug caused by my Synced Account Settings addon for U47 Live so if you have that addon and if you can't move the camera up and down with the mouse, set the "Camera - Vertical Lock Speed" game option to a normal value and then redo your settings save in the addon.
The bug is due to the new game settings + the addon restoring former values after login, your "Camera - Vertical Lock Speed" setting will be a negative value which will cause the vertical camera move to stop functoning until you go in the settings and set it (easily fixable in a few seconds and won't come back if you redo your [Save character settings] & [Save ALL settings] saves).
