Inline 7?

[dusty]

Ok,changed all my plugged up emmisions that Rawze recommends to clean,i bought all new stuff,2012 w900 2250, bought inline7 data link and have not been able to get it to work.installed programs etc,try the validation tool and it says not connected,error code 134,invalid device,and the data link is inline 7 2.6.0.21,and when you plug it to computer it says setting up inline 6 and when finished it says inline 6 ready? I have not a clue,unless just a piece,any help would be greatly appreciated
