Help! MW3 Console will NOT open for me!

Hey, well my problem is, after 2 hours of searching, I can not open my Remote console. The 'Enable Remote Console' option is set to YES. I have went into about 30 different servers and tried opening it there, I tried re-installing my mp_config, I tried restarting my PC, I have tried doing it manually in mp_config, I have tried alot of different stuff. I am open to suggestions. Thanks.
PS: It worked before, like I got it to work about a week ago. I think it was last sunday. But after Monday, nothing.
