I’m frustrated

My iphone4 app appears to be frozen

All lists show the same entries for the last four days and they are the most recent 'checked and deleted' entries from just one of the lists. I have also deleted a large number of dastardly duplicate entries on a couple of days prior to the freeze problem, so have no idea if that is still an issue. Today is the first day I figured out that I can see my lists online, but syncing my phone while signed in here isn't helping either.

I was enjoying the app and finding it quite useful. Any help to get it back without having to repurchase would be appreciated.
