Software is stable, our security system can crash and bsod it depending on what programs you're running. The bsod you have is probably no related with the cheat itself, but with a blacklisted program running at the same time of it.
Rating ESP as 5/10 because it don't have visibility colors is far from being honest. We will add some blink effect to the ESP when it's visible, so you can choose using it or not. It's better than just doing more colors options and it's pretty easier to use.
