download dip-bot and create a folder and name it what ever, then extract the files form dip bot
into that folder, customize the settings how you like, better off at aimhight:65 or 67 so you don't get constant head shots and get banned faster, once you do that run dip bot and open dirty bomb , you will notice that the window of dip bot closed, its fine, it does that so it doesn't detect it as a third party program running for dirty bomb, they do that so you don't get banned for 2 days, most of the times that works.It should work, as far as my understanding that's how it works in my book.
