This problem is resolved in SmartConnect 2010 Build 39. If you have maps you need to import from build 38, you can correct the XML file by doing the following:
1. Open the XML file in Notepad
2. Go to Edit – Replace
3. In the “Find what” box type this: <RunMapAsUser i:nil=”true” />
4. In the “Replace with” box type this: <RunMapAsUser />
5. Click on the “Replace All” button
6. Close and save the XML file and then perform the import again. The import will run correctly.
