Mike,

The DataPump Studio does not have a password (or user account system).

The pump process itself is done via Windows TaskScheduler and you should be able to remove a task and re-create it again via the DataPumpStudio.

There has been no maintenance for a couple of years - mainly because it simply works - but since it is using DataFlex v16 we should consider an recompile and redistribution using DataFlex 20.
