Well to start off let me just tell you then your waisting your time
Because all the hack's are detected and well even if you do get the hack working you will be kick by punkbuster sooner or later.... it's sad i know :/
And well try to run your injector as administrator also if the injector show's then the hack has been injected go to bfh and try pressing Home and Instert butons on your keyboard. And you made a misstake by unistalling your antivirus software because who know's what kind of websites are you viewing and what kind of files are your downloading you might get a nasty virus so my advice to you is to install it back and well just desable it the next time you want to do some hacking.
Well Good luck trying!
