show not valid from usb after firmware rollback

I had to rollback the firmware since my iPad was unable to update due to its age. Luckily I had kept the show right before I did the first firmware update. I hade a few changes in between the two saves but this could be a problem for others. Is there a way to still use the show I saved with firmware 1.6 or are they incompatible since it was a rollback.

they are incompatible…
