Hi John, don't worry about the signature blurb, you can trust it and install quite safely - last re-install I did, I had exactly the same - Win 7 64-bit. Sorry John, just re-read your post, I thought the 64-bit drivers were already in 3.13 and later, but if not, do as Bryan suggests, then go to Device Manager, and try to go to Driver Update and force the Driver to load.
