Can't get maps to show in base camp

[r_rod10]

Hello.  I can not get my maps to show up in base camp.  I have read and followed the tutorials.  I am trying to get the South Central United States with installer.  I clicked on the download button, the install wizard came up and i followed all the directions. I clicked finish at the end and it said successful installation on computer.  I then followed the tutorial directions and opened up base camp.  I clicked on the drop down menu, but it only showed TOPO US 100K  and NO MAP.  The map I had just downloaded did not show up.  The tutorial said that if it was the first map it may not show up.  I then continued to follow the directions and clicked on the VIEW menu and then MAP PRODUCTS, but the map was still not displayed.  I do not know what else to do or where to go.  Any help would be greatly apprectiated.  Thank you!
