Age of Empire 3 shows error

Hi,
I am a lover of games and I have the Age of Empire trial version and I play during my free time. Recently, it has been throwing an initialization error as shown in the image below. Any help in solving this will be appreciated. I have reinstalled it several times with no luck.

Direct3D initialization failed, Possible causes:
Old or corrupted graphics driver,
Direct3D improperly installed.
Hardware acceleration disabled.
Starting the application with the workstation locked.
Please check the log file for more information.
