I had all my students create a map package and upload them to our class group on ArcGIS online (using 10.1). Now I am trying to save/download all the map packages and open them in ArcMap but I get the same error message for all the map packages: "error reading package contents". I get this error whether I try to open directly from ArcGIS online or if I first download and then try to unpack the package in ArcCatalog.
This is a graded assignment so I don't know what to do. It worked when I tested it before assigning.
Thank you.
