Installed r59. Yes, I had to create the folder. It's still giving that error code though.
c2project\object-folder\object-type\behaviors\behavior-type
Line 21, Column 17
If I assume correctly this is pointing to the runtime js file on which line 21 reads
behaviorProto.Type = function(behavior, objtype)
I will delete the files, re-download, unpackage in the behavior folder and give it another try.
I have the paid version now so that rules out the +100 events possibility.
