For these who has problem with "Waiting for target process to run..." - Extract all files and go in C:\Program Files (x86)\Steam\steamapps\common\Dirty Bomb\Binaries\Win32 and put there all files so yah reinstall dirty bomb to the normal place,then start dipbot.exe via admin and start game normally on steam.
post back any results.

Also i made a bit of a boo boo when i said about hoe to change the aim key "EDIT: to change the AIMKEY you need to use Virtual-Key Codes for example 0x02=2=right mouse button (You only need to yse the number at the end) and 0x10=10=Shiftand 0x58=58=x key. x"
You can't just put aimkey=58 you have to put aimkey=0x58 (just an example) to find more just visit the link in the first post
