i have a problem running only directx 9 programs. the rest of the programs like programs that use directx 8 libraries work fine.even the simple program does not work. pls help or else i will die :P here is a sample of error: --------------------Configuration: DX Project 1 - Win32 Debug-------------------- Compiling... Main.cpp Linking... Main.obj : error LNK2001: unresolved external symbol _Direct3DCreate9@4 Debug/DX Project 1.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe.
