Hi, I have the exact same issue. I was watching Netflix and it asked me to upgrade from v4 to v5 of Silverlight. Now nothing works in Silverlight and each browser just shows that the plugin has crashed. I have deleted the files for Silverlight on several occassions, deleted caches, restarted the computer several times and it still will not work. Reinstalling v4 Works fine, but Netflix will not let me watch using the older version of the plugin.
I have a Mac Pro (Server) 2009 with 1 Quad Core 2.66 GHz Xeon, 8 GB 1033 DDR3 RAM, 2 Monitors, 2 NVidia GT 120 graphic cards running OSX 10.7.2.
