Oh if you can't get it to work!
Try this
The dll file is hidden so goto your folder
then tools
folder options
then tick show hidden files then the dll will show but will be kinda seethrough
next right click the dll and press Properties
then click general and tick the hidden option off the OK.
now you see it and open the injector and it will say waiting for Engine.exe
now you can take off show hidden folders if you want.
Thank me if i helped
