Ok, I'm going crazy. I was having problems with silverlight crashing in firefox so I decided to uninstall it and reinstall it. So I did everything I thought I needed to to uninstall and tried to reinstall. However I get this message "Microsoft silverlight browser plug-in can't be installed on this disk. A newer version of this software already exists on this disk." I've searched all over the internet and followed everybody's suggestions on what to delete. I have no clue and I need silverlight to run Hudl. PLEASE PLEASE HElP.
