OK, I now know how your show got corrupted. We had a bug in the 3.2.0/3.2.1 that if you saved your show to USB stick before saving to the HD on a Hog 3 we did not save a clean backup. (this is now fixed in 3.2.2 b3337 that was released today).
If the show is still on the Hog3, launch it, back it up to the HD the drag it over to the USB stick.
