CoD4 Cracked Server Error

Hey guys,

Every time I try to connect to a cracked server, I get the same error message, which is "code_post_gfx_mp.ff is different from server". Could anyone tell me how to fix this or at least tell me what it means?

Thanks,
Fusalet

try this ip:
this working for me!
type in console: connect 217.172.183.27:28961
maby u just pick the wrong servers.
if this insn't working for you, try reinstal cod4?
