Hi, I'm hoping someone else has had this problem and can help out. I've had the EOS-1v's data link cable and software for quite a few years, and it has always been a bit unstable when it comes to connecting the camera to my computer. At the moment I have a lot of data to transfer, but I just can't get the software to acknowledge that the camera is connected. It always just comes back with "Unable to communicate with camera. Check that the camera is in data-transfer mode and the cable is properly connected". The transfer mode is selected and the cable is connected properly. It's extremely frustrating. Does anyone have a fix or a work-around? Is there a particular sequence I need to be following regarding plugging in, putting the camera in transfer mode, and running the software? Any help would be much appreciated.
