EmbeddedQuartzSystemListener.ERROR_0006 (while trying to change db)

Hi there,

I installed biserver ce 5.0.1 on Windows7 64bit machine and am trying to change database to Postgresql9.2.
Now I get "Pentaho Initialization Exception" error on a browser.

pentaho.log shows as below.
Could somebody tell me how to solve it?

Thank you,
