"nothing works right" isnt much to go on.
But probably you have to install some upgrades and extra programs that were removed when you put it back to factory condition
for netflix it would probably be the adobe flash player from this website
But i am guessing in the dark unless i get a better description of the error.
It is very late here but if you can wait till tomorrow i can get you my phone number and remote into your computer and straighten everything out for you. There is an additional charge for that however.
