Return of Reckoning

managed to get game loaded now all i get is cinimatic credits setting quit . with a blank box on top right of screen

this comes up on running game

Data.myp:
System.Exception: You need to stop application currently using the following file: data.myp
at MYPHandler.MYPHandler.WriteFileToArchive ...

when trying to run launcher i keep getting pop up saying

WAR.exe - system error

this program can't start because d3dx9_34.dll is missing from your computer. try reinstalling the program to fix this program.

anything i can do apart from redownload the game ?
