Roll back to Windows XP, mate - that seems to be the only OS that provides some semblance of stability to the infrastructure of this game: I speak from experience and many months of frustration
Seriously, you don't.
Anybody still running XP needs shooting.
Running an 11 year old OS on modern hardware is just crazy. It cannot make use of the advanced hardware features.
Run Windows 7 if you just cannot move forward and use a new interface, use Windows 8 if you're open to change.
