I would also like to know this
Every time I try to run Liberation for MW2, and error message that says: "You are attempting to use Modern Warfare 2 Liberation on a system where a circumvention attempt was detected. If you are using one please cease to do so. Please support our project and actually donate." comes up. How do I fix this?
Liberation doesn't work on the current version of MW2.
Even though Mods don't work on the current version, a user might know how to get them working.
