Same for me, just can't get it to work! And I do play in English. My version of gatherer is v2.99.0.0448.
I copied the file Gatherer.lua from the the SavedVariables- folder in the WTF-folder.
I pasted it into the Cartographer_Import folder.
I logged in to wow with both gatherer and enabled. I get the chattext Cartographer_Import: Done importing notes. But when I turrn off Gatherer the notes disappear and I can only see the ones I have found after I got Cartographer.
