"Silverlight plugin isn't loading"

[nbubna]

Whenever i try to watch Amazon Prime in Helium, it gives me this message at the top:

"The Silverlight plugin isn't loading and might be blocked by your browser. Please see the Amazon website for additional troubleshooting help. Error: 7303"

In the center of the black screen is a little "Blocked Plugin" button with an arrow, but clicking it does nothing.

Any ideas? I get the same error for this URL: http://go2.microsoft.com/fwlink/?LinkID=149156

This happens with both version 1.9 and 2.0 for me.

Same here with version 2.0

Reinstalling Silverlight fixed this for me for 2.0
