I have Silverlight installed. I have just started using Skydrive. To try it out I uploaded a few pictures and videos. Easy to do, however when I went to view the video the screen was very dark. A banner at the top of the screen stated that Silverlight was required and there was a download button presented. I have no idea why it is invisible to SkyDrive. Checked out MS Answers Forum/SkyDrive (holy moly, what a dreadful forum) but I could not find an instance similar to this. Not sure if I need to turn something on somewhere or not. I clicked on Silverlight and there was nothing there that I could see. My webcam works just fine. I assume it is required to view the video from IE. It is a wvm file. I can view the video just fine on my PC so I am a little confused as to why the screen is so dark on IE and why Silverlight is being requested when it is already installed.
