Modern Warfare 2 uses proprietary compression methods within its .ff files. When you try to extract the "zone" from a multiplayer patch (like patch_mp.ff ), it's often entirely encrypted. A common problem users face is an "ERROR: could not find zone: 'ui.ff'" message when the game launches. This error usually means the game file is corrupted, not properly signed for your console (e.g., PS3 vs. Xbox 360), or the tool you used failed to decompress the file correctly.
Errors can occur if the game is installed on a corrupted external hard drive. Moving the game to your internal drive often resolves persistent file read errors.
