I'm looking for a convenient raster edition tool for ArcGis 10.1. I have found and registed Raster Editor Extension (Minimum ArcGIS Release: 9.0) =>

but I can't use it.
When I'll try to start edit a layer, apears a window with a message: "SetSymbolSefaults - Invalid property value".
I can't set the Edit workspace variable too. How do I create a temporary database for raster edition?
please help me
