Error starting up

everytime i try to start the game, the screen goes black ad after a while an error message comes up saying " Unable to initialize 3D output. Please verify that you have installed DirectX 8 and an updated video driver. Click the URL below to open a web page with more information. http://www.guildwars.com/support/3d-init-failure.html"
Im no computer wiz so if anyone could help me, that would be great. but im realy mad right now because i cant play!

The message is basically telling you to update your drivers for your video card. Depending on your video card, go visit their main site and search for the driver download page.

thanks! i can play again
