I'm trying to connect my phone to my laptop. I'm running vista 64 bit. I'm connecting via usb, then I follow the steps to mount the sd card and windows recognizes the phone as a disk drive (the autoplay option even pops up). Then I go to open one of the folders on the phone (like my music folder) and I get a message saying to insert a disk or that no disk is inserted in the drive. The sd card is not corrupt and is installed correctly. In fact the phone works fine when connected to a computer running windows xp. But for some reason it is not working on my machine running vista 64 bit. Can someone please help me??? I've been on the phone with my laptop manufacturer and T-Mobile and nobody knows the problem.
