What Operating System (OS) do you use?
Did you download the latest Windows Updates, Graphic and Directx Drivers yet?
Did you try just the standart Mirror or the Alternative Downlod Mirrors aswell?
If these dont work for you, you can try it with this Mirror.
Ensure, that Crossfire.exe, Gameguard.mon and Gameguard.des got full access through your firewall and turn your Antivirus program off for the Installation.
And depending on which OS your runing, you should install Crossfire as Administrator for Windows Vista / Windows 7.
