Railworks system error
After resetting my pc and losing everything i reinstalled Railworks in steam but when i went to launch it said the program couldn't start because d3dx9_43.dll is missing from my computer, and to reinstall to fix the problem, so i put the ts2012 disk and installed it then it updated to ts2014, and i went to launch but once again the d3dx9_43.dll is missing
any ideas??.. And i did verify the game cache but it said everything was good..
