hpl271: anyway, in game's image is like cut in a half and controls don't work. for instance, when i select a voice and press space, it's like i select the one below. maybe i should try different graphical settings?
It's always a good idea to try all modes and see which one works the best for you.

For the second problem, launch the game in windowed mode, see if it helps. If so, then it's probably scaling issue.

In Nvidia Control Panel set scaling mode to 'maintain Aspect Ratio' (it's under Adjust Desktop Size and Position). Go back to the game folder, edit *.conf file in Notepad and set fullresolution=desktop
