Are you connecting directly to the camera or are you using a card reader?
There are many reasons to use a card reader and this might very well be one of them. If you are using a card reader, and this is failing, you might consider just manually dragging the images from the card to a folder on your computer. Before there was ingestion software, that's what I did.
BTW, CS6 is no longer supported and Windows 7 is also a bit long in the tooth. You might be running out of options and may have to upgrade your software one of these days. Obviously that's your call.
