So I've got Windows 7, and when I plug in my BlackBerry 8900 it recognizes the media card, and it makes that noise that its connected, but when I start Desktop Manager (or AppLoader) the Pin says None (AppLoader is blank). I've uninstalled, reinstalled DM, I've deleted the driver from device manager, I've unchecked the power management thing in Device Manager, I've changed the USB port used (tried more than 3 different ones). I don't know what else to do. I've tried my brother's 8900 and it does the same thing. This tells me its probably a Windows 7 problem. Does anyone have any idea what it might be? My brother has Windows 7 on his computer as well but his works with both of our phones.
