Hi all,
Rover 75 V8 & Windows 10. 

These scanning tools are new to me.
I finished the installation today, got the green blinking light, registered the laptop.
However it through up an error message, could not read error codes.
Under "petrol engine", I've selected Rover 75/ZT V8 260. Under Protocol, I've selected Ford. Gateway is also offered. 

Any suggestions where I've gone wrong? 

Thanks & regards
Max P
