So a little over a week ago, I accidently clicked something on the left ruler
margin bar or whatever it is, and now whenever I open a new document, it
starts typing at the very top of the page. It used to have a gray marking on
the vertical ruler about a few inches down, and whenever I try to change it,
it doesn't work. Is there any way to reset to the original settings or
reinstall Word without buying it?
