Election Day is here but can't vote yet...

This morning at showed up at my polling place, Farrer Elementary in Provo, at 7:00. The poll workers were there and ready for me and the two others also there to vote. We received our voting cards after they were programmed for our precincts, but all three of us received the same error, "Ballot not found for this voter, please insert supervisor card." After trying to erase the cards and recode them, the same errors came up and the supervisor called for assistance. After a while on the phone she said that they didn't know yet what was going on and they are having the same problem throughout Provo. I'm curious as to how wide spread the problem is. I felt bad for the poll workers whose hands are tied. Some have been through the trainings multiple times on the Diebold machines that we're using, but they couldn't do anything to fix the problem. I've have to go back later in the day to vote.

I'm curious also on why the polls are open only from 7:00 AM to 8:00 PM. Is it to give the voters a 13 hour window to vote, or is is to have the polls only open for that specific time. It may be time to revisit voting hours. I certainly don't have a 13 hour block in which I could vote today.
