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:

    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.
