Well, when you dowload a hack, you get 2 files
1 is hack(.dll)
and other is injector(.exe)
Now, first of, you rename them, like mpgh.exe and mpgh.dll
Then, when hackshiled starts loading, you open injector.
N: Both files must be with same names in same place.
Also, if you have vista or win7, run as admin. And, if you have 64bit, you need to find injector, that works for 64bit.
