Looks like the program's window is too large for your screen setting. First step would be to set your resolution higher.
For this, right-click somewhere on an empty bit of your desktop. Select 'properties'. Go to the 'settings' tab. On the bottom left there is a slider, set this as far to the right as it will go. If you've got a fairly standard CRT display, this might be something like 1024x768 or 1280x1024. Press 'OK' and your screen should now resize. Try the program again to see if everything fits on the screen now.
If the slider is already on the right side, let us now what setting it's at, and what sort of graphics card and monitor you're running.
