Jenny I installed Adobe flash player and java. Do you think they hurt my system.
No. Most people have them installed and most computers ship with them installed. You just have to make sure to download them from a safe site so they don't have anything "extra" that installs with them.
I just don't think they helped with your problem using the walkthroughs link.
Before installing them I didn't have any trouble watching netflix. Now I get a lot of error message. They gave a lot of options of what to do but I don't like making any change in my computer. I have to shut my computer down and start up again. I can watch for about a hour and that's it.

Copy down the error message next time you see it so we can do a search on what might be causing it.
