cant find my replays

The replays can only be viewed through the game itself. You can find the replay files in your Documents/Crossfire folder. On windows XP the path is c:\documents and settings\username\My Documents\Crossfire\Replay. On Vista the path is c:\users\username\Documents\Crossfire.

Once you have located the file, go to a site like mediafire.com and upload the replay. Then send a PM to [cf]reports and include all important information like the hacker's name, what hack he was using, etc. Whatever you do, do not post accusations publicly though.
