I have recorded a screencast that shows on how I try to load an arff file to rapid miner http://www.screenr.com/PkKs
The issue is that I am getting the following error:

Can anyone tell me what I did wrong and how do I fix this?

    The last line in the error message says "OutOfMemory" - i.e. your RapidMiner does not have enough memory. To train the decision tree. Please try to increase the value of MAX_JAVA_MEMORY in RapidMinerGUI.bat in the scripts folder of your RapidMiner installation. If that does not help, you could also try to use another decision tree operator, e.g. J48 from the WEKA extension.

    And please, next time you have a problem, simply post the XML of your process - that way we can reconstruct your process with a few clicks instead of watching a minute long movie.

    Thank you, and good luck with your process! If you have further questions, don't hesitate to ask.

    Cheers,
    Marius
