Combat Arms Hack not working?

Game booster should not interfere with hacks, just antivirus could... disable it while injecting is recommended and in certain cases needed. Game booster anyway is useless, it can be useful to a legit player to close useless application that could be detected as hacks from server log, but for you it will NOT boost your game but instead make it slower. I think you shouldn't use it, but feel free to do what you want if you believe in magic.

1. Yes, you need to inject the .dll each time you run the game.
Nexon detect the hacks very fast anyway, if you care about ban, don't hack, you will be banned there's no way to evade it at 100% if you hack everyday. But if you feel lucky, use the hack only few hours after release and then delete it.

2. You CAN'T inject more than 1 hack, they will not work.

3. They're automatically "un-injected" when engine.exe is closed. That's why you need to "re-inject" each time you run the game.

Few additional notes for you:
The lag could be caused from windows 8, try CA without any hack and check. Plus, not all hacks work on windows 8.

The game works just fine without any hacks. It's just with the hack it lags. You have answered my question perfectly except for number 2. Which is answered indirectly. I meant inject the hack, play for a bit, quit, then play again and re-inject it. Which, is again, answered indirectly. I'll try updating my drivers and make a "hacking account" solely for trolling purposes. Then again, they can ban my IP, can't they?

I couldn't find an update for my driver, and now the hack doesn't work. at all.

Whelp, that's not possible. xD I'm talking to the programmer now on her thread. I'll consider this solved.

They can use your IP to trace your accounts:
If you get ban for hacking, they'll check your IP, if there are other account they'll be banned too even if you did not hacked there. Plus, if you keep cheating, they'll make periodically trace and in the worst case, even an HWID ban.

If without hack it doesn't lag, then the problem is the hack and the code can be changed only by the autor, we can't help you. Else, we could suggest something...
