"[SOLVED]Process Documents from files does not produce anything"

p3kka

Hi,

I'm a new user for Rapid Miner. There are a few problems that I have encountered.

1) I can't update the program directly from the GUI because of the workplace's proxy settings. Is this causing any harms? (for example is this a problem? PM WARNING: Could not open http://rapid-i.com/wiki/index.php?title=Text:Tokenize: connect timed out)
2) I've watched some videos how to process textual data and trying to implement something. I've installed Text Processing extension. The problem is that I can't produce anything when I'm trying to use "Process Documents from Files". This warning is the only thing that appears: "PM WARNING: Error creating renderer: java.lang.ArrayIndexOutOfBoundsException: 0". This tells nothing to me. Results tell that there are no examples. Any solutions or proposals?

This is the code and those text files are in .txt -format

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="6.0.002">

...Or is the problem with the "Starter" -license? I've tried this application earlier and used the free trial option and if I remember right, it worked well back then.
