£10 leads only work with the free version.
the license for the full version is built into the real VAG COM lead hence why they are £200.
there are ways around this if you search the internet hard enough

I got the full version and can thoroughly recommend it

saves a trip to the dealer and being fleeced everytime they hook it up

also you can do your mates VAG cars for a few beer tokens

you'll soon make your money back
