Macbook Pro/Silverlight issues

The most recent question & reply I can find in the Community is a year old, so I am asking again.

I have a Macbook Pro running OSX version 10.8.2 (purchased in December of 2012)

I had been watching movies, TV shows, etc. on Netflix for several months with no problem. Last week while in the middle of a show, a screen popped up stating:

Silverlight Installation Problem

Error code: 2103

I uninstalled & reinstalled as suggested. Quite a few times, actually. I sent my question to Microsoft Silverlight Support, but did not get a response, of course. I have read online about others with defiinite issues with Silverlight for Mac.

Last night I tried reinstalling once again, and that time it worked. I was ecstatic, to say the least. I have been watching a TV series, and very much wished to continue. I watched a couple of episodes last night. This morining I was able to watch a full episode (40 minutes) and most of the next episode. THEN, the screen went blank, but the audio portion continued to work.

I know I can uninstall/reinstall Silverlight again and hope it fixes the problem. But is it only a temporary "fix" as it apparently was last night? I guess I really want to know:

Has anyone actually had any luck in REALLY "fixing" this Microsoft Silverlight/Mac issue? Or should I just forget about watching Netflix on my Mac?

😠 😟 😕 (Yes, I'm angry, sad and confused).
