To answer your previous question about what an injector is:
Basically, you need an injector in order to make the hacks that people create run (which are usually little .dll files amiright) A .dll by itself cannot just run, it needs to be within the processes memory stream so that it can tap into the various functions of the program. And injector does just that, it allocates some nice virtual memory for your little .dll before creating a module for it to go into so that it is loaded into the processes memory. Cool eh? So anyway, it's basically a must for any sort of .dll hacks, without it they won't run. For most injectors you just press "browse" find the .dll and press OK. Then get ready to inject. But seeing as this injector is such a crap one, you have to go into a file, put your .dll there and rename it specifically to what you want (fucking gay) and then inject it manually. Don't use this one, find a good injector there are plenty around, especially in the Combat Arms section.
