After Aaron´s tip, no more log erros, but after I´ve entered the admin user and password, the console hangs, and in the Windows console window opened by the .bat file (remembering, I´m using a Windows machine to run the Management Console), appers the error:

==================================
First I remembered that I was using the old console code, and copied the new code from the new FDS install (the /bin and /lib folders), but the error was the same. Second, I´ve upgraded the Java version of my machine - was 1.4.2_3, now it´s 1.5.0_06. Same error.

Any thoughts?
