I'm plugging my phone into my computer (Windows 7), but when I try to view sd card contents I am getting "Please insert disk" notification. It recognizes that I have it plugged in and it charges, but I can't access any of my phone files. I was able to do this 5 hours ago and since I've had this phone, this has never happened before. Before when I plugged my phone in I instantly got a pop up asking if I want to see files, but now I can't even access them without that. No idea where this new problem just came from. This is really frustrating as I want to be able to do this. Any help is appreciated, thanks.
