Troubleshooting


While using Maps Over Time you may
encounter a blank screen at some point.
This may occur for two reasons:


A) You have no maps selected.
Make sure that at least one of
the three maps is checked "on"

B) Your selected map(s) may not
cover the area of the city you have
selected. Zoom all the way out and
recenter on a mapped area.
