Guild Wars won't play

Well i have Guild Wars Faction and deicided to play it(after like 2 months of not playing it) and it wouldn't play for me.It played fine when i first got it and now it wont.I keep getting that message about the initiating the 3d thing and how i need to get Directx 8 and a updated video driver.I downloaded the included Directx 9 that came with Factions and i tried getting an updated video driver but it said mine was already up-to-date.

All help is appreciated.

What graphics card do you have installed?
