Can you explain how it is not good? Do you see the picture as many pictures one upon other?
If so install patch. But if you have downloaded the game from
http://www.lbahq.com/ then don't install patch, because the version of it has already fixed all bugs.
Yes, as Joullele has stated, you need the patch if the video is not working as it should. However, please download and install our version, as this version has automatically been patched for all currently known issues.
