"I am following the mentioned thread and of course picked up the free DS4 version as soon as I got the notification"

Hope it's working well for you. I've always been puzzled why so many people seem to have problems running DS. I can't even run DS4, my "system" is so laughably below the specs, but DS3A and every other version has worked pretty flawlessly. That's with a wildly eclectic mix of applications, development software, an oddball mix of dlls registered etc. Puzzling.
