I download the C5 update for Primvol to try it out before purchasing, does this update run in demo mode when I load a new scene it wants a serial number so I select cancel and try to load one of it primitives but it crashes with a " Nil pointer Error has occured, File: Primitive.cpp, Line:1863".

Does anyone use this plugin? and does it work under C5.1 std?

Thank you for any help.
