You should be able to ask the person you bought it from.

check dashboard->Appearances->Widgets and then look in the widget

No does not help,not there.
Maybe I can look inthe php code,what file would that be in?

check the 2nd widget in the left sidebar
if this doesn't help and you want some private consultaiton, send me a PM
