icon issue

I recently moved my Weather Display install from an old Windows XP laptop to a newer machine running Windows 10. I used the method found on this site to move the WD C:wdisplay to the new machine. Thanks to all the guys that responded to my earlier question about installing on a USB drive. I was able to get enough room on the system drive to get it installed. Everything is going fine but I have 2 questions. On my old machine the WD had the icon(?) that showed a graphic that changed to show the time of day and rain or snow etc. I believe the proper term is icon. Now it has a nighttime moon view that doesn’t change. I know this must be a simple setting that is incorrect but I cannot find it. Help would be very welcome. Second, does 2.7GB give me enough headroom to run WD?
