You're in the same position as me, I couldn't get mine to do anything either, cable (I'm using a wired connection) shows up, drivers load, it can 'see' everything but you can't edit anything. Someone on another forum said to try other versions of techstream, an older version worked for them, but I've tried 10,11,12,16 and 17 (from memory, often multiple releases within each) and using virtual machine or native in Windows 10 and all to no avail. I could buy a different cable but don't want to drop £60 on a 'claimed good' version in case it's something on my vehicle that's preventing it so I'll wait and when I get a service done at a specialist I'll ask them to take a stab at it.
