Hi Allison,
The webmap you were looking at "a59a0210f99847fab743c233aa3ed367" was actually a legacy leftover when the original journal was built. It referenced layers that are no longer accessible - that's why you were seeing the errors. I've now removed it from the journal and unshared it so you shouldn't see it any longer.
The current webmap being used is: http://www.arcgis.com/home/item.html?id=e904305c4b224955b3060bffbe755770
Let us know if you have any problems with this one. You must have an organization account to see the individual service layers in this map as they're subscription based only.
