Injecting Issues :[

So i am using windows vista and i am trying to inject a .dll that is said to work on vista (Jeevin MPGH hack). The issue im having is the injectors are being weird...its obviously not the injector's fault because ive tried 3 diffrent ones now

FI injector - Tells me the injection fails upon start up of Engine.exe but no error occurs...

xSyR1Ng3x- Tells me it injected properly but once the game starts up, but no menu appears when i press the corresponding button.

I-nject (one of the PerX extensions)- Does the same as xSyR1Ng3x

I am logged on as admin and running everything as admin as well. If anyone would like to tell me what i am doing wrong, it would be much appreciated. :]

This is a strange issue, I would try it with your anti-virus turned off, it might work then, post back with results!
