EMC.ini /ServoToGo

Hi,
I am in the process of setting up the ini. file to suit the STG card
,but every time I try to run EMC (without the hardware connected )I
get a fault on the 3 axis and the PC locks up completly.I have tried
changing the fault polarity but I get the same result.EMC worked fine
before I configured it for STG8, anyone got any ideas? Thanks ,Jim.
