Vrml editor tree/subtree expansion java exception error

[Mahmut]

Hi all,

When I try to expand tree/subtree to edit animation objects 3D World Editor in Matlab 2013a, I encountered the java exception error at the end of the post.
My system has GeForce GT 630 graphic card with latest, Intel Core i7 CPU, Windows 7 64bit pro.

Could you please point me in the right direction?
Many thanks, with regards
