VIctor SPX Firmware update

Ok, so my teammates and I are using the Victor SPX motor controllers this year, but since we updated the firmware the controllers have been “skipping” data that they used to receive, so I wanted to know if this is a Firmware error or the motor controllers are damaged.
Thanks for your attention.

Your problem statement is not thorough enough for us to venture a guess about what is going on. What does “skipping data” mean? With what language, in what situations? What hardware is the motor controller hooked to?
