Injector error

I start up injector > browse it > auto inject > close after inject and I can't get into crossfire. First I get the blackscreen in game and suddenly everything get closed.

Help me please?..

It's either,

A. the hack is already detected.
B. You didn't run your injector as an administrator
C. The injector you're using is detected
D. You don't have the requirements. (.NET framework, Redist. etc.)

1. Use undetected injector and dll's
2. Make sure you install the proper requirements
3. if your OS is windows XP 32bit or 7 32bit use injector that really work in 32bit users
4. if your PC is windows 7 or vista make your you run the injector as admin
5. Press thanks if I helped
