problem with themes editor projects

Hi Gurus!

I'm having a problem with SAP NetWeaver Developer Studio.

Version: 2.0.14

Build id: 200509100215

I'm using SAP/UR Design Themes' view. I'm trying to import a Design file (.zip) and the Developer return me error: "The Design could not be imported. Datamanager could not be initialized!"

Can anybody help me? I don't have idea about this!

Thanks a lot!!!!
