Yeah, I forgot I updated my manufacturing line to use a newer firmware for new devices and those started shipping. Latest GUI's didn't support those, so I had to quickly release an update. Oops. Slaps forehead.
Jason, I got my replacement case the other day & the screws went in with no problems this time. As Whiznot said, thank you so much for the very fast delivery of the replacement!! I love the sturdy design of the case.
