Guild Wars 2

Hey people!
I have a problem with my Sony Vegas programs where they get stuck on the Initializing DirectX Plugins.
I’ve contacted Sony with their Tech Support and I’m waiting almost 8days without a response; their forums aren’t any better.

Cany anyone help me with this here by chance?
Vegas Movie Studio HD 11 Platinum
Sound Forge 10

Forgot to mention that I was told it could very well be possible that a game on my computer has a DirectX plugin that is interfering with Vegas would anyone know which games that could be? to name a few I have Guild Wars 2, Deus Ex HR, The Witcher 2, Battlefield 3, Metin2, Dark Souls(and the mod to make it look better, idk if that could make it do that, this problem may have been before I even bought Dark Souls on PC) Steam as well where most of those games are on, BlackLight:R, Oblivion(with no mods) Team Fortress 2. There may be a few more.

I know that a mod will remove my post for typing here but I’d like to get some answer at all even though this forum probably doesn’t know much about it.
