Hi, I'm not sure if you've posted in the correct section of the forum...
Anyway the most important thing is select the correct process...
It is helpful to use Chrome or Firefox as there's a "AUTO" select of the process which most of the time won't go wrong unless you opened a lot of browers then there might be a problem as well...
Another thing to note is that some game needs to be paused at certain part of the loading screen and others at the main screen so look out for the comments...
There's another problem that fails the hacks is whereby you're so unlucky that the first time you tried, they got patched just before you did...
That should be all for now...
Good luck trying~
Bye~
