I tried to move a smart object in blackpearl 90x beta, using the SmartObejct Service Tester app. It allowed me to "copy" it to another location by dragging.

well, after doing this, now I cannot connect to the smart object server anymore. Error is

 could not connect to server "XXXXX:YYYY". Message : 'Object reference not set to an instance of an object"

any ideas on errors that would cause this? 

Update: After rebooting the system, I still cannot connect to the smart object server. I can also not connect to the smartobject server via the Visual Studio K2 Object Browser plugin
