I have tried connecting when engine running and same thing stops communicating after short time of 40 sec with PC,  its as if the PC freezes up with no activity until key off & unplug USB link then message ECU not responding appears.

Have tried running in XP mode on PC and same thing but now PC goes blue screen with message your PC ran into a problem and needs to shut down: stop code:multiple IRP COMPLETE REQUESTS.

Can you help? do you think its a PC issue or ECU issue?

Cheers
