Well, first of all you should have posted this is the correct section, the help section.
Secondly, most of the public hacks are files that need to be injected so if you don't feel comfortable using injectors then you're most likely not going to have many hacks. Injectors are really easy to use, you just browse for the file you want to inject and set it to inject into Engine.exe
And the fact that most of your hacks aren't working probably means you set them up wrong, they don't work on your system, or they are detected. Make sure you read the entire post on hack releases and check the date that it was released.
