Corrupted schedule causing reboots

[wingetj]

It appears that my schedule on a VIP722 is corrupted. Whenever we try to add, edit or delete a timer it causes the VIP722 to reboot. It appears to be doing what it should, the the live preview window goes black and then the whole thing reboots. However, it does appear to make the change to the schedule that we were trying to do.

Is there a way to force a check of the schedule and fix corruption? The diagnostics menu options were not helpful.

Any ideas before I call Dishnetwork and get the run around? Thanks!
