Process failed, why?

Hi,
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
• Stack trace:

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

Hi,

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

Can you share the process itself?

Best,

Martin

Hi, 

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.

Best regards,
Natalie
