Is there memory card installed in your blackberry ?
If so - when your device is connected to your desktop (device keyboard has to be unlocked) - then additional removable drive has to appear in "My computer".
If there is no removable drive - check your usb-cable. Perhaps there is a problem with your usb-cable.

Try to reinstall your BB Desktop Manager, if that does not help - try to use one of previous version.
If your device is not broken and cable is good - there is something wrong in BB Desktop Manager.
