Null pointer exception when trying to use Concept Drift Plugin

Hello all,
   
   I am trying to use the Concept Drift Plugin (developed by J. C Bose) but I always get a Null Pointer exception. I have tried with different combinations and with simple datasets (for instance, the dataset from Process Mining book - Aalst) and I always get this error. Could anyone help me with this plugin? It is a problem in ProM 6.9 version?

Kind regards,
Denise

    Hello Denise/Sousa,

    To see what is going wrong with this plugin, I need some additional information. Can you run ProM 6.9 by going to the folder where you have installed it, and then running the ProM69.bat file? This opens a command prompt running ProM 6.9 where lots of messages will be displayed, for now please ignore them. Then please run the plugin as you did before. When the plugin crashes, some diagnostic messages will be displayed in the command prompt. Please copy these messages here.

    Kind regards, Eric.
