Uninstalled and reinstalled. Still the same problem.
I do not see any problems, why not install crack?
the only reasonable reason not to install it - game through the "GameSpy Arcade".
You can try to install "CCleaner" and clean up the registry.
You can also just download the game from torrent and there already is a licensed version 1.01.0011, this simply does not need to install the crack.
I do not understand that in this difficult.
