rekordbox linked properly

i have 2 cdj 2000 and djm 2000 and the thing i need help with is the little snitch program i need a step by step procedure to make sure it's correct cause when i try to set it up i still get just the rekordbox program coming thru and when the edb file is added it says it doesn't exist. my players work,and i can drop files on the players and they work it's just i see rekordbox pop up only.
