Custom mail event stopped

Custom mail event stopped

I have a mail event that was working before I left for the holidays, but now it appears that it isn't working.  Seems the last time it worked was around the 25th.  They're both enabled.  I'm not sure what if anything has changed.  I have re-set the execution time to see if that would trigger it to occur, but even after the time passed, the debug information shows the next execution time is in the past.

data2
{
    execute event on '2012-12-31' at '11:33' daily
}

I'm not sure how the debug information on that screen is supposed to help me.

S.No. Schedule Name Next Execution Time
1 data2 2012-12-31 11:33:00.0
2 data 2012-12-31 16:00:00.0
