I use this hack and nothing happens
I have the same as you
1.I opens BF3
2. Roll up in game and while it's loading run the hack as admin. (Launch exe. File "Public BF3 Hack")
3. Successful inject written
4. Press insert and nothing happens!
If you have skype, you can screen share and we all can see whats wrong.
Hitting insert again would do nothing, In this program Insert has a function that activates another function. If Insert doesn't have a function or something in your system isn't allowing insert to activate what insert was trying to do it's meaningless no matter how many times you hit it.
