Can't Download Apps via Zune

[KayEee]

Hello,
I just purchased a new HTC Arrive. I need help downloading Apps via Zune. I load Zune on my PC and the connected my Arrive to the PC. The connection looks good. Some Windows applications were updated; I am able to move pictures and videos to the phone fine using Zunes drag and drop...but... when I select an Application to drag and drop nothing happens.
Hase anyone had this problem that could point me in the right direction?

Thanks!
