Inpa noob needing some advice

Ok first of all I'm sorry if this is in the wrong section, I was looking for a diagnostic section but couldnt find it, secondly I apologise if this has been asked before, I have searched all day but I keep getting mixed results.

I bought this cable online and it came yesterday http://www.amazon.co.uk/Best-Price-I.../dp/B00PFLX92U

I spent all yesterday doing a fresh install of XP on the laptop (used to run Ubuntu but there was limited support) and I installed INPA. I didnt use the copy that came with it I downloaded the files from a David Mc on 4shared so credit to him if he's on here?

Anyway long story short after all the hassle of installing I connected it up to the car but I can't seem to access anything electrical, I can access the engine bits and make the car do things ( today I did a throttle reset and checked / cleared some codes) but when I try to access things like the airbag (my light is on ) INPA says it can't connect to the control unit. Also on the main home page of INPA it shows that the battery is ON but ignition is OFF.

I know the cable works because like I said I've been able to clear codes and do some engine stuff (vanos test was one I tried too) how come I can't access the airbag settings and other bits?

People say that pins 7+8 need to be soldered, but this cable is meant to be K + D can compatible, I took it apart to check if they were soldered but it's not as easy to see. The case comes off but then the pins are kind of inside the chip so i dont want to pull the chip off to check in case I break it.

Any help from someone more technically minded than my self is highly appreciated.

Edit : Also, is there a couple guide of INPA's features explaining what option does what and so on? I managed to read live data from the engine especially the o2 sensor as its on its way out. But I dont really know what I'm looking for. There's a ton of guides for installing it but I haven't found one what explains all its features and sub menu option etc.

Cheers again!
