Got the same issue just looking through the forum no clues as yet!
It appears I did not configure the drives correctly the 1st time around. After not having received a response I decided to wipe and start over. Whatever I did wrong the 1st time, I did not do the 2nd time.
When loading the USB device I now see the "Locked" portable media and an additional drive that appears as a CD Drive however is now executable so auto-run loads the Access Enterprise application. I'm assuming the application drive was not configured correctly.
I know this may not help your particular situation. Good luck.
