CheatEngine problems

Hello there. Some days ago i just used CheatEngine to level up some characters, whatsoever. I always use speedhack to x500 cuz' it's gonna take 100 billion years to make those levels without speedhack. Today, i tried the speedhack and the CheatEngine just stops with, eventually, error: CheatEngine has stopped working. I reinstalled and get a bigger version, v 6.7 but still the same thing, and this only happends on DBD. Any help? Thanks..

500 is way way to high now. Only go to 15 max I would say 10 is more than enough. Also it will freeze for about 5 minutes and look like it is timing out. Just go make some coffee and come back you will be all good.
