Netflix fails.

[Nicolas]

It still gives me the PC error even after reinstalling Silverlight. Go Microsoft products!

*turns to Smart TV*

You have to clear out Silverlight's cache, apparently. I had it the other week. Can't remember where it's at, honestly. Netflix will tell you though. I'm sure something like CCleaner would find it too.

This may help.
