I have been trying to update to CL14 for a long time now and cannot get it to work. I started with no drivers, downloaded the SW upgrade program, and followed the instructions. It usually doesn't allow the moment to install the necessary drivers, and when I occasionally get it to install them it brings up an error message after i try and download....something about an "e - dll unable to open usb serial port. code:87". Can anyone help me out? I have a Vista 64 bit laptop
