Can you zip up the data file and send to me?
Also give me the exception code as .txt file.
A screen shot of the GUI would be good too.
A tip can be, use GSB on the defaults, then vary things a bit.
Changing lots of things at once when your not familiar with GSB is more likely to land you
in unproductive areas.
