Joe,
Google has discontinued that map service. The alternate is to go into the maps option for a locality, then go down to the second option below the map "ACME mapper topographic map." That will give you the topo map already set on the coordinates provided in the mindat locality file. It can be moved around like the old Google map; however, the cursor on the map does not move with it like the Mindat tourmaline logo used to.
