Windows media player files will not play. I downloaded the plug in but does not show up under plugins. Why won't it load?

Whenever I try to play a wmv file through firefox it will not load. It was not a problem a few weeks ago. Under plugins it is saying I do not have windows media player. So I tried downloading it using the troubleshooting directions from firefox. But it still will not show up under plugins. Any help would be much appreciated.

np-mswmp in your Installed Plugins listing (in More system details to the right of your posting) is the Windows Media Player plugin for Firefox.

Yes, I see that it is there. But it is not listed on my list of plugins under add ons on the tools menu.

It appears as Npdsplay.dll in the Add-ons > Plugins tab.
Windows Media Player also uses the two Microsoft DRM plugins.
