yeah none of those things are particularly useful, you tried the 1.40 .exe and plugins didn't work because you dont have the registry fix (that i linked you in pm)
scriptGL just doesn't work for everyone, mav had the same nvidia vidcard that someone else had and he could never run scriptGL so its not even card or OS or driver dependent
you might be able to figure it out, but personally i'd just use non-scriptGL configs on that system, or go back to 7/8.
unless somehow greyhound appears and drops some knowledge on us but that would blow my mind
