Thanks, Man.
That's the approach I initially thought I would take, but on second look I'm not sure if it's ok to do this and simply "overwrite" the current setup. It crossed my mind that it might be better to remove the current setup (I don't know how to do that, but I presume it's possible) and then run the wizard, as you suggest, to set up the new configuration.
I'll keep researching for a bit, but in the meantime I'd sure appreciate any help or opinions.
Cheers
AA
