Process failed, why?

When I try to run a simple process (you know the introduction: Add the Titanic data as input and connect the retrive box output to the result with a line, then pressing Run) I get a report saying this:

  • Exception: java.lang.IllegalArgumentException
  • Message: null

Why did the process failed? 
I totally new to this program, just downloaded Rapid Miner Studio today and noticed that my license is "uninitialized".

    this looks odd. Even if you did something wrong you should receive a proper error message.

    Can you share the process itself?

    Problem solved. It looks like it was my license that wasn't initialized. When I logged into RapidMiner later and retried to run the process, everything worked fine. I don't know why, but it seems like there was an delay between the registration and when the license started to work. 

    Thank you anyways for your help.
