RQMJunitSelenium Adapter doesn't start

Hello,
I'm trying to configure RQM - Selenium integration following this: http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0/index.jsp?topic=%2Fcom.ibm.rational.test.qm.doc%2Ftopics%2Fc_selenium_adapter.html

I'm blocked in starting the Adapter.
Here is the error from the command line:

Launching Command Line Adapter...java version "1.6.0_45"Java(TM) SE Runtime Environment (build 1.6.0_45-b06)Java HotSpot(TM) Client VM (build 20.45-b01, mixed mode, sharing)Adapter is reconnecting. Using saved configuration information from Config2.ini Exception in thread "main" java.lang.RuntimeException: BASE64 input is invalid because it is the wrong size        at com.ibm.rqm.adapter.library.connection.Base64.decode(Base64.java:163)        at com.ibm.rqm.adapter.commandline.QMCommandLineAdapter.main(QMCommandLineAdapter.java:240)The command line adapter did not run, exited unexpectedly, or was killed.This can happen if java.exe was not found in the PATH,or if java.exe is too old or not compatible (the version of JAVA required is 1.5 or later),or Configuration File does not have write permissions,or some other error occurred.Please refer to the readme.txt file in the adapter package.

The Configuration Information is saved in Config2.ini and I have write permission in the working directory.

Let me know if you need further info.
