P.S your scanner does it have user instructions or does it presume you to be an expert, I've used icarsoft scanners before with reasonable success on modern cars ?
Well, neither really
The main complication is getting the software installed. That is quite well documented here

The next thing is that it doesn't have a menu where you select the car that you have, you have to know what ECUs are in your car. The list for an MGF/TF is here

So for your car you would have to select "Transmission" and then "MEMS3 CVT / Stepspeed". Or if you had an airbag light on you would select "Airbag" and then "RC5/EC5".
This will get you into the ECU that you want to analyse and from there you really don't need instructions.
There are just three big buttons saying "Read Error Codes", "Erase Error Codes" and "Live Data" and that's it.
