SH3 Editor Sensors.dat need advice Please

[fly999]

Hi Guys need some help with this please .

This morning i decided to change a few entries in my "Sensors.dat"

I am using GWX3
So using SH3 Editor and printing out which changes to make following "Makmans" post i did the following :
1) made a back up of sensors.dat ... and a system restore
2) made the changes and then saved the file .
3) ran SH3 which started load but then went to a Black screen !

believing i had made an error somewhere i reinstated the original sensors.dat file and loaded Sh3 again , no dice ,,, still black screen

ran system restore ,,, SH3 loads as above but then goes to a Black screen again,
Please note i have sound ,,,,, but no visual !!

Any help or advice would be greatly appreciated
