Gatherer database importing problem

Gather Mate has a nice data importing feature that allows you to have many nodes already marked on your map.

Unfortunately the import button is grayed out on the addon. I am unable to import the date through the GUI in wow.

Does anyone have a working version or a way around this?

I tried copying the data from the database download at wotlkdb. I found the Herb section, and copied it in what I thought was the correct spot in the Lua file. But that did not work either.

My goal is just to have the herbs already marked on my map.
