I spent a little bit of time developing a presentation using the ArcGIS Explorer Online presentation maker. It worked just fine for a week and then the day of the presentation (a half hour before) I went to double check the presentation and I got an error saying it was corrupt (ArcGIS Explorer Online: The map could not be opened. The document is invalid or corrupt). I am wondering how it could become corrupt without me doing anything? And if it does become corrupt in the future, how do I repair it if it is in the ESRI ???cloud???? I can open it just fine in ArcGIS Viewer Online, but I really needed the presentation I made.
The map is: Carbon County Trails Committee
