I am having the same problem as the OP. Here is what I have tried thus far. Also, the code has been downloaded multiple times (just in case it was a bad download).
Computer #1 (Windows 10), unetbootin, Sandisk 8GB, USB 2.0: FAIL (DICE boots straight into game)
Computer #1 (Windows 10), unetbootin, Sandisk 32GB, USB 3.0: FAIL (DICE boots straight into game)
Computer #1 (Windows 10), unetbootin, PNY 16GB, USB 3.0: FAIL (DICE boots straight into game)
Computer #2 (Windows 10), unetbootin, Sandisk 8GB, USB 2.0: FAIL (DICE boots straight into game)
Computer #2(Windows 10), unetbootin, Sandisk 32GB, USB 3.0: FAIL (DICE boots straight into game)
Computer #2 (Windows 10), unetbootin, PNY 16GB, USB 3.0: FAIL (DICE boots straight into game)
Computer #3 (Linux Mint), unetbootin, PNY 16GB, USB 3.0: FAIL (DICE boots straight into game)
Computer #3 (Linux Mint), ISO Writer, PNY 16GB, USB 3.0: FAIL (DICE boots straight into game)
Note: There is a Rocketek Bluetooth USB Dongle on the USB extension cable that is located inside the coindoor. I remove the Bluetooth dongle prior to inserting the USB stick with DI code (version 1.50).
ANy guidance would be greatly appreciated.
