Notes Regarding Pitbull Pro 2.4.4 A somewhat tricky app to find these days due to the Hotline community being very small. It's still vastly better than the vanilla Hotline client however. Simply unstuff the program somewhere and open its folder, then open the folder that says something like "PLACE IN PREFERENCES FOLDER" and place the pref file from that folder where it's supposed to go and the program should be registered.
