I can't redownload cf

Well, you should go to the download section on the CrossFire/Z8games homepage, here:

http://crossfire.z8games.com/downloadS2.aspx

First try that big orange button, which I would assume is the default download precedure (after making sure that you have deleted all old CF files already).

If that fails to work, try one of the bottom right-hand links to other downloads which may help your computer to handle the CF application (perhaps your graphics card isn't up to par or some other technical issue like that).

If that also fails to work, find your way around Google and find a site where you can dowload CF "Mirrors," which are similar downloads. Here's 1 Mirror Download of several others, you may have to try them as well.

And IF ALL ELSE FAILS, look at your computer's settings and check to see that cookies are being allowed, and that CF is being passed through your Firewall unblocked. Also, the Avast* antivirus system, if you have it, may be interfering; you can see the article on it back in Tech Support if that's the case.

Hope this helps!
