I had a problem watching netflix in safari, an error message came up saying I need to uninstall and re-install silverlight. This was also present in Chrome. Error code 2105. I followed the instructions, removed silverlight, downloaded it, re-installed it and deleted all browser history and cookies relating to netflix. Netflix started to work fine for about a day, then the error appeared again. This has happened for 4 days straight now where I need to uninstall and re-install silverlight just to watch something. Please can someone help me? Why is this happening?
