Hope someone can help. I've got a Blackberry 8520 mobile which I charge through my laptop using a usb cable. I also use this method to open files and download videos and photos from phone to pc. The problem is that lately I've noticed that when I connect the usb up to the laptop the box that used to appear asking how I want to open files doesn't appear anymore, so now I can't download my photos or vids to pc. I've tried clicking on My Computer when the Blackberry is connected but it doesn't appear there either just the usual c, dvd and recovery drives.I hope someone can help maybe I've unticked something by mistake but can't find out what. Anyway any help is much appreciated.
