It would be easier to try to help if you had told us what you tried, but
first check to make sure it hasn't been shrunk to zero lines high. Move the
mouse cursor to the very bottom of the screen and wiggle it slightly up and
down, trying to turn it into a two-headed arrow. If it does, click and drag
that top border up to make it the size you want.
If that doesn't work, it may have also been moved to another side of the
screen. Try the same on the other three sides.
Finally, if none of those work, go to
, click T, then under Taskbar,
click Taskbar is Missing.
