Hello @trishsman
the 2 cards are in your collection
i test to donwload the card DB 318 - US center data -- all ok for the moment. -- edit download ok for me.
try this in the program :
Setting - Advanced - left clic mouse synchronize with server - wait a little, control if you can download - if that not work then
Setting - Advanced - right clic mouse on synchronize with server - rebuild all. control if you can download.
if that not work, restart your computer. the more simple.
