Which trainer is working?

So I'm new here, know nothing about MW3 trainers, cheats. Have no idea where you guys are now. I tried this trainer
http://www.mpgh.net/forum/404-call-d...1-7-413-a.html
and it shows "MW3 not found"
Is it not working?

Ensure you are using the MW3 Steam Version

Use "Searx updated version 6.0" that is by far thee best unlocker out there

I totally agree with 34thca. Definatly use SearX. Easily the best.
