Cannot add Maps from Esri in ArcGIS for AutoCAD

Discussion created by on Jan 15, 2014

if I try to add a Map from Esri I get this error Message:

"DependencySource" must be in the same thread as "DependencyObject"


Adding a Service is possible without any problems.
I'm running on AutoCAD Civil3D 2014 64bit and ArcGIS for AutoCAD 300 SP1.

Anyone an idea?
