Netflix Won't Stream

My Macbook Pro has been updated, so flash, silverlight and everything are current. I've recycled the wifi, logged in and out, and restarted the computer. I can't seem to get Netflix out of this funk.

I'll be watching a few episodes and everything will go fine. If I stop for a second and log into face book or my email, netflix will suddenly decide it doesn't want to load. I'll click 'Resume', it'll be a black loading screen but the url bar at the top will only fill up a quarter of the way. It'll remain like that for hours without loading. After a few days I'll be able to continue watching whatever I was watching, but I have no idea what made it stop streaming or start up again. This has been going on for about a month now so I figured it was time to figure out what I can do about it.
