Silverlight Woes

[KerishME]

I completed an upgrade request with Silverlight earlier in the week and now Netflix will not work. I then tried to uninstall Silverlight using the instructions from Netflix and other recommendations online. I went into the HD Library folder and threw away the Internet Plugin Silverlight file. I also got rid of anything I found using the Spotlight check. I tossed the Application Support Silverlight files and the Receipts files. I did not see any WPFE files. I have tried several times but when I go back and try to install the version that Netflix wants me to use, I get an error that says "Microsoft Silverlight Browser Plug-in can't be installed on this disk. A newer version of this software already exists on this disk."

I am on a Macbook Pro running system 10.6.8

Any help would be appreciated.
