Made a troubleshooting guide here. usually you can fix it if you remove the files from dump folder and reinstall dxgi.dll if not then you have to reinstall everything.Apologies for the trouble, I followed the guide on page 34. I have an issue that hearthstone closes every time I start it with the service running. I get the "warning" sound from SKIF, but heartstone immediatly closes.
If I do not have SKIF started, the game starts fine.
btw i have had this happend quite frequently when i put the .dds files in the dump folder :P
