WIndows Vista Agent ¿Working or not?

[cyberalf]

Hello, i just finished installed babel Server and get it running ok on a Ubuntu Jaunty server, ¿Anybody can get John the ripper working on the agent installed in windows vista?.
Of course there is no Vista Agent, only windows agent but i have it running on 3 vista and a 2008 server sending data witouth problems, the only thing that is strange is that john gives error as i detail above.

07-07-09 11:01:06: Execution number 1
07-07-09 11:01:23: John did not make a log file
07-07-09 11:01:23: Error while deleting C:\Program Files\Babel Enterprise\\util\john.pot
07-07-09 11:01:23: Error while deleting C:\Program Files\Babel Enterprise\\util\john.log
07-07-09 11:01:24: Successfuly copied XML file to server.
07-07-09 11:01:24: Next execution on 60 mins

The rest as you can see is working correctly, ¿anyone has it working 100%?
Thanks in advance.
P.D.: For details on how to get windows agent working on vista please tell me.
