I've gone in and done updates to firmware 2 or 3 times in a row, had to exit the program and go back in to see the latest update.
Are you sure your v7.5 software is up to date? What build are you on?
You have to update the firmware on your v2 and your computer. Go in an update the firmware again through v8. I've got this a few times and EVERYTIME it's because one or the other isn't updated.
