Injection Problem

Hello, I am using Perx injector. I have downloaded Chocolates v3.1.dll and I injected it into engine, I had it onto auto so it did it on its own but, when the game oppened I hit f10, and insert and no menu was coming up. I run on windows 7 64 bit. I have a cutsom computer so everything is fast. what should I do. Also when I get this resolved, how do I use the menu like after it is up, arrow keys and enter?
