Hacks strait up not working

Hey everyone. Sorry if this has already been posted/asked but I have been having trouble getting hacks t work lately. I used to play and hack alot but then i took a break and now i cant seem to get anything to work at all. I inject the hack and the injection is sucsessful and i dont get D/Ced but then the hack just doesnt work.

Any help at all would be apreciated
Thanks
