Hey guys, I'm fairly new to windows phone. I bought two Nokia Lumia 520 and i tried connecting it to my windows 7 x64 PC. It asked me to install an app, so I installed it. But when I try to browse files in my phone through my PC, it shows nothing. I tried syncing through media player it still doesn't show up. Really need help guys. The other phone works just fine. It lets me browse files and also lets me sync up with windows media player but this one doesn't. Could really use some help.
