I am trying to attend an online class that uses Silverlight to broadcast to participants. I have installed Silverlight, the Silverlight website confirms I have it installed, I have restarted my computer and Firefox, but when I log into the course, I am prompted to download Silverlight.

I am missing my class. What can I do?

I'm not seeing a recent Silverlight (4 or 5) plugin in your system details list.
Is the plugin that shows as 1.0.30715 the Silverlight 1.0.30715 plugin?

In that case you may be out of luck if the website requires a later Silverlight version that isn't available for your PowerPC computer.
