Hey Michael, Hey David, I have a similar problem with Referenced Assemblies.
http://groups.google.com/group/grasshopper3d/web/referenced%20assemblies1.jpg http://groups.google.com/group/grasshopper3d/web/referenced%20assemblies2.jpg I'll try with with other dll's of this software, but if I'm using "Visual Studio 2008" I have not trouble with it. Thanks for your help! All the Best! Dimitry
