Feed 43 - great feed filter, some problems

Hi I love soupio and have used all its components for a few months now.

I filter twitter by feed43 and soup doesn't seem to poll feed43.com/any_old_feed.xml

- feed is added ok
- imports just one item
- doesn't update (tested this over a few weeks)
- other feed readers have no problems with initial import or updates

Many thanks for your awsome tool
