If you find that the images on the screen do not seem to be aligned properly, that nothing happens when you are clicking on buttons, that you cannot enter things into text fields or that there is strange empty space on the screen your issue may be that your display settings need to be changed.
Find your display settings through the Windows control panel and check to see that your settings or DPI is set to 100% or 96 DPI or normal depending on what version of Windows you are using. Then accept the new settings and restart the game.
