RhinoNest 0.4 within Grasshopper

 I haven't switched to version 0.9.0006 yet, so I'm still using the previous version. I installed and downloaded RhinoNest 0.4 for Grasshopper. When I use the multi-sheet nesting component and plug in the curves to be nested and then the rectangular sheet to nest within, the component turns red and gives this error message:

Solution exception:Could not load type 'ReportObjectSheet' from assembly 'RhinoNestTools, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

 Any idea how to correct this?

Thanks,

Vern
