I have a blackberry curve8520 and just recently it has stopped letting me connect to my laptop. i used the same wire as before and it wont let me. I plug the wire in and, how the clock is supposed to pop up, it comes on then goes and keeps doing that if you understand. i am just wondering if its my blackberry, the wire or my laptop itself. i have blackberry desktop manager installed butim not sure my blackberry is running the latest version. please help!
