Error masterkey in BatchExecute

I have a problem when I try to execute a Knime workflow via batch procedure.

when i try this

knime.exe -consoleLog -noexit -nosplash -masterkey="12345678"
 -application org.knime.product.KNIME_BATCH_APPLICATION    

it ask me for the encryption key in a new window
I pass the key as a parameter, but the application ask me for the key every time I execute the batch procedure
How can I avoid this request?

Thanks in advance

Sorry the master key does not work as expected in KNIME 1.3.5, see:

Thank you for the reply.
I will wait for the 2.0 relase.
