d3dx9_37.dll file is missing help please?

Hi to all,

After installing the Football Manager 2009 demo I got a problem.

When I click on the shortcut to the game I get the message that the d3dx9_37.dll file is missing. I install the file into the system but FM09 then just tells me that there is a problem and the program will quit.

I therefore remove the installed file and try to run the dxwebsetup.exe following the game.

Now the message "an internal error occurred. Please refer to dxerror.log and directx.log in your windows to determine problem"
