Try running PerX injector as Administrator , try it until you can get it to work . I have the same problem as you . I kept on injecting till the hack works . Hope this could help to solve your issues .
For blackshot garena users, it is detected, but im not sure for Europe. And if you are facing problems while injecting, try running your injector as administrator if it does not work, try another injector like PerX etc.
