well considering that it doesnt crash it can be a good thing
1. make sure you are injecting into Engine.exe
2. Make sure the injection auto closes.
3. if nothing pops up saying ur mising _____.dll you shouldnt have to worry about it
4.make sure its an up to date hack that works (check the forum and see if others have this problem) and that its for CA NA or EU which ever you use
try these out and let me know how it turns out
dont forget to press thanks
