Fixed... It was two problems... first my user need to be able to "log on as batch job", and then I was creating a file in my desktop, but I set a different user, and this user has not right to write at this folder... I only figured out when I look at log files... I was not receiving any feedback at history tab, so I was thinking that task are not running, when at real it was running but with issues. Maybe an improvement at history tab be a good suggestion.
