Had the same problem, even with fresh install of Windows. Fresh install, installed 12.8 drivers, crash. Another fresh install, 13.4 drivers, crash. Another fresh install, 12.8 drivers, SDK, crash.

Seems GPU mining is ignored now, developer is like a bitch in heat over USB mining bollocks.
Gave up with not getting any answers on here, tried latest BFGMiner with 13.4 and it's working no problems.
Thanks.
P.S. Try disabling USB hotplug if you're not using USB devices --hotplug 0
