Been trying for hours. Whenever I use my cmd pointer to access something, it crashes.

What info do you need? I'm not getting much info myself other than the fact that I crash whenever my cmd pointer is used.

What do you mean with "bad update btw"? My struct was updated, I tried the struct that the guy sent(they were the same btw). So how is it the struct?

compile in debug? injector is mmap or lla?

I obv compile in debug as that's where I have my debug info generated, however the release build also crashes. As far as it goes for the injector, I use processhacker with -insecure, but does that really matter?
