I am trying to load a shock wave file with extension .dcr
But in the browser,k it throws error "The application requires an Xtra(SWA
Streaming Xtra) that either does not exist or failed to initialize properly.
Please make sure the appropriate Xtras are in the Xtras folder(s)."

I tried uninstall with uninstaller and shockwave was installed again. But it
keeps on loading

can anybody help me?
