I'm experiencing some problems with the feeder. I recently tried to upload a new feed but the feed was rejected because it was missing the UPC field. I turned on the auction feilds and now I get the following error:

I tried a upgrade to 1.6.8, but still get the error. Any idea what I need to do to get things working agian??
