I recently downloaded APEX Data Loader version 27.0.1. My colleague has a batch job that does a bulk upload of records to our salesforce account. I tried running the script on my computer and kept getting an error. I narrowed down the culprit to be the output of the command line when running encrypt.bat. 

When running the command line prompt "ecrypt.bat -g seed_text_here", the script is expecting the output to be just the key that should be saved to key.txt. This is consistent with the online video tutorial located here: http://www.salesforce.com/_app/video/data_loader/help/data_loader_cli.jsp

However, when I run "ecrypt.bat -g seed_text_here" on my computer, I get the following output: 

2013-04-24 15:06:21,050 INFO [main] security.EncryptionUtil main (EncryptionUtil.java:304) - encrypted_password_key_here

It appears to be an issue with setting the logging level. Any ideas on how to change this? 

Thanks.
