Switching to DX9

[blacksox88]

Hey, guys, i just started using dolphin over the weekend, and after some hours searching the forums and fiddling with the settings, i've decided to switch from openGL to the dx9 plugin. however, when i go to the plugins tab in options, the only option i get for graphics plugin is OpenGL. i have the original directx9 plugin, and a second dx9 plugin that i downloaded, stored into the plugin folder, but it still wont appear in the actual program. do u think you know what the problem is? thanks!
