It dont work if you bought it from steam...
Because then you have a command line that looks something like this:
H:\Programmer\Steam\Steam.exe -applaunch 21760

what u have to do in steam is go to the My Games tab, right click on WIC, go to properties, then under the General tab click set launch options. now u can add "-stabilityfactor 10"
