Hey, loveuk. I see your problem, and I'll try to give you some reasons why this may be happening!
*The hacks are possibly outdated, detected, or patched.
*The installer of which you use is detected.
*You may have to inject manually, rather automatically.
If any of the suggestions of why you are unable to install hacks are true, try to get a [RELEASE] hack, and an undetected installer. This time, inject the hacks manually.
Goodluck, loveuk!
Your friend,
