When exporting a .CMAP file from CMaps Analytics designer, it does not seem to import into DecisionPoint.
The solution is changing the file type from XML to All. Then you can import any .CMAP file into DecisionPoint.
WHY DID WE CHANGE THE FILE?
Newer versions of Google Chrome were blocking the browser from downloading XML files that CMaps Analytics generated. It was determined that creating our own file extension would ensure downloads work across browsers, and also supports future repository publishing and searching options for platforms like Google for Work.
