Error with IvM when I want to visualise the graph

I receive this error when I run the visualise() of the InductiveVisualMiner.

Apparent everything is ok in the application, because the graph is showed by I can't animate it. Maybe I'm wrong but I think what I doing is right.

This error says that the lpsolve libraries are not available to the running program.

1) get the lpsolve directory from a ProM installation and copy it to your program's location. For instance, from C:\Users\sander\.ProM66\packages\lpsolve-5.5.1\lib.
2) add the following command-line arguments to the Java VM: 
-Djava.library.path=.//lib/LpSolve-lib/win64
(and change to the location/architecture that you're targeting)

Thank a lot, because I'm develop an application with InductiveVisualMiner, I have to resolve the libraries by my self. So I downloaded in this links Ipsolve55_win_64, Ipsolve55j, and follow this tutorial to copy the libraries in the correct directory. After that, everything run fine. Hope this can help someone.
