Can't get iPhone or iPod to show up in iTunes?

My iTunes automatically installed the latest version, it use to just come up on the left side and show my folders and the iPod name. Now it doesn't show up or have the left side folders, I can't add any music. Best answer 10 points.

Added (1). It shows me nothing on the corner, all it says is view and add to. I have like 200 songs in 5 different folders and it doesn't show my anything.

The iPod and iPhone now shows up in the top right corner
