Oh, that's why it won't work: 'crack' is bad. Style XP has a fully-functional, expiring demo. You install it, see if it works with your computer, and after 15 (or 30) days it requires you to register to continue using it. You might uninstall the cracked version and try installing the official version. If the cracked code is in your Windows registry, the software may continue to not work.
I can't vouch for the other software, but from their websites, they all do about the same thing: get rid of the green "start" button and customize colour schemes. Good luck.
